Laurie Anne Walden, DVMOsteoarthritis is very common in cats but often goes undetected. In most cats, joint pain doesn’t cause obvious signs like limping. Instead, it causes changes in mobility and behavior that can be misinterpreted as normal aging. Cat owners’ recognition of these changes is the first step in diagnosing and relieving joint pain. Cause Osteoarthritis is a chronic disease in which the protective cartilage in a joint wears down. Eventually the bones and other structures in the joint deteriorate, causing pain that worsens over time. Degenerative joint diseases like osteoarthritis can be caused by trauma or by problems with the structure of a joint, but often the cause is not known. Senior cats are by far the most likely to develop osteoarthritis. Younger cats can be affected too. Osteoarthritis in cats most often involves the hips, elbows, knees, and hocks. Cats can also develop degenerative joint disease in the spine. Various studies have shown that between about 60% and 90% of cats have evidence of degenerative joint disease on radiographs (x-ray images).[1-3] Not all of these cats have pain, though, at least not at first. Signs In cats, signs of joint pain are subtle. Cats tend to hide signs of pain. Osteoarthritis often affects joints on both sides of cats’ bodies, so they don’t develop lameness—it’s hard to limp with both front legs or both rear legs at the same time. Signs of osteoarthritis in cats reflect their limited mobility, reduced activities of daily living, and general grumpiness caused by chronic pain:
Diagnosis The most important diagnostic tool is cat owners’ observations of signs of joint pain at home. Treatment is often started just on the basis of behavior changes consistent with pain. Cat owners can use questionnaires like the Feline Musculoskeletal Pain Index (https://painfreecats.org/) to record and score their cats’ signs of pain. These assessment tools help veterinarians diagnose joint pain and are also very useful to track changes over time and monitor response to treatment. Cats with signs of pain should receive a physical examination to be sure the signs are caused by joint or back pain and not by something else. A full orthopedic examination of a cat is challenging (sort of like examining an uncooperative bowl of jello that doesn’t tell you when it hurts and won’t trot on leash), but sometimes an examination reveals joint thickening or other physical changes of osteoarthritis. Radiographs can show evidence of degenerative joint disease but aren’t always needed. The decision to use imaging depends on the individual cat. Treatment Never give a cat pain medication, including nonprescription over-the-counter remedies, without consulting a veterinarian. Some medications that are safe for people and dogs are very dangerous for cats. In cats, joint pain is managed with a combination of nondrug and drug treatments. A multimodal approach (using several strategies) tailored to each cat’s pain level and living conditions is the best way to help relieve chronic pain in cats. Nondrug treatments include weight management, adjunctive therapies like acupuncture, dietary supplements such as glucosamine, and environmental modifications like ramps, steps, soft bedding, and litter boxes with low sides. Drug options are more limited for cats than they are for dogs, but a number of drugs are available. A new injectable treatment for osteoarthritis pain avoids the need to give a cat a pill by mouth.[3] References 1. Lascelles BD, Henry JB 3rd, Brown J, et al.

In the United States, the chance that a person will catch monkeypox from a pet or give monkeypox to a pet is very low. Transmission between people and pets is possible, though, so the Centers for Disease Control and Prevention (CDC) has developed monkeypox guidance for pet owners. This article summarizes information from the CDC and the American Veterinary Medical Association (AVMA) and is current as of August 24, 2022. See these links for updates:
How Monkeypox Spreads Monkeypox was first discovered in 1958 in monkeys and since then has been found in many animal species. Rodents and other small mammals (not monkeys) are thought to be the reservoir species that maintain the virus. Human infection was first reported in 1970 in Africa, and monkeypox has occasionally appeared in other parts of the world. The United States had an outbreak in 2003 after pet prairie dogs were housed with infected animals from Ghana. The 2022 global monkeypox outbreak has involved at least 75 countries. The monkeypox virus is related to the virus that causes smallpox. The virus infects the host through the respiratory tract, mouth, eyes, or broken skin. These are some of the ways people and animals are infected:
Most transmission during the 2022 outbreak has been through close, direct contact with an infected person. Animals at Risk One pet dog has contracted monkeypox, most likely from direct contact with its owners (this was the first reported case of human-to-animal transmission). Chinchillas, prairie dogs, and some types of rabbits, mice, and rats can be infected with the monkeypox virus. Many wild mammals are also susceptible to infection. Cats, guinea pigs, hamsters, and cows can be infected with other viruses in the same genus as monkeypox, but whether they can also be infected with the monkeypox virus is not yet known. The CDC says that it’s best to assume that any mammal can be infected. There have been no reports of infection in animals that are not mammals. Signs of Monkeypox in Animals These are some of the signs that infected animals have developed:
These symptoms are nonspecific. Many conditions that are much more common than monkeypox cause the same symptoms in animals. Diagnosing monkeypox requires laboratory tests. Precautions for Pet Owners: CDC Guidance

Pets that are urinating in unfortunate locations need urinalysis because inappropriate urination can be a symptom of a medical problem. Routine wellness checks, especially for senior animals, often include urinalysis. Urine is also collected for bacterial culture and other tests. Urinalysis includes measurement of urine concentration, chemical analysis, and examination under a microscope. The results are affected by the age of the urine and the way the sample is collected. Urine begins to change soon after it’s voided, so urine samples need to be very fresh, ideally delivered to the veterinary clinic within an hour. The collection container needs to be completely clean, with no residue from food or cleaning solutions that can affect the chemical test results. Debris in a urine sample interferes with the chemical analysis and microscopic examination. Urine can be collected either at home or at the veterinary clinic, depending on the reason the sample is needed and individual pet and household factors (such as the animal’s temperament and medical conditions, owner’s ability to collect urine, and distance to the clinic). Home urine collection is fine for most routine urinalysis, but check with your veterinarian to be sure it’s appropriate for your pet. Sometimes urine needs to be collected in a sterile manner at the veterinary clinic. In these cases, urine is usually collected by cystocentesis, a technique using a needle inserted directly into the bladder. General Urine Collection Tips

Collecting Urine From Cats
Photo by Tran Mau Tri Tam on Unsplash Laurie Anne Walden, DVMPets need stool tests to screen for parasites or help find the cause of diarrhea and other digestive system problems. Collecting a stool sample at home is the least stressful option for the pet. The alternative is for someone at the veterinary clinic to use a loop to remove a little bit of stool from the rectum. This option yields a much smaller sample and can be unpleasant for the animal. A fecal test for parasites involves mixing the stool sample in a flotation solution and either spinning it in a centrifuge or leaving it to sit in a vial for a certain amount of time. The material at the top of the solution is then removed to a microscope slide to look for parasite eggs that have floated to the surface. Sometimes a tiny bit of stool is smeared directly onto a microscope slide for examination. Fecal analysis can also include chemical tests. For all of these tests, the stool needs to be fresh and squishy enough to mix or smear. The age and condition of a stool sample affect the results. Parasite eggs can dry out or hatch in old stool. Hard, dry feces is very difficult or impossible to prepare for testing. Stool that has been sitting outdoors for a while can contain fly eggs or larvae (maggots). Liquid diarrhea that’s soaked into paper or cloth can’t be mixed in solution to test for parasites. Here’s how to collect a stool sample to get the most accurate results:
Photo by Lucas Ludwig on Unsplash Laurie Anne Walden, DVMSocializing young kittens and puppies means giving them positive experiences with things they’ll encounter throughout their lives. Building positive associations early in life helps animals feel comfortable with new people and new situations. Animals that are well socialized when they’re young are less likely to develop fear-based behavior problems (like aggression) that could put them at risk of being sent to a shelter or euthanized later on. Sensitive Period for Socialization For kittens, the window of opportunity for socialization is very early: from 3 weeks to about 7 to 9 weeks of age.[1,2] The sensitive period is the time when a young kitten’s brain is most receptive to socialization. During these early weeks, a kitten is exploring and learning, developing neurological pathways that will help the kitten learn in the future. After the sensitive period, brain development shifts; kittens don’t make positive associations as quickly or easily and they’re more likely to be afraid of new things. This is why it’s so difficult, if not impossible, to convert a semi-feral adult cat into a cat that can be happy living as a house pet. You will have noticed that the sensitive socialization period for kittens is nearly closed by the time they’re typically adopted or purchased. Socialization needs to start with the person caring for the mother cat and newborns. When you adopt or buy a kitten, continue providing socialization (at the kitten’s comfort level and pace) to reinforce what the kitten has already learned. The socialization process should always be positive. Don’t force kittens to interact with strangers or other animals if they’re shy, and don’t push them to be near things that scare them. Let them choose whether to interact. Give them room to walk away and let them hide if they want to. Use positive reinforcement (food or play) to encourage them to interact and build their confidence. The following suggestions are adapted from the American Veterinary Medical Association.[1] For more tips, check out the First Year of Life page on the Cat Friendly Homes website: https://catfriendly.com/life-stages/first-year-life/ Socializing Kittens Before Weaning

They are volatile compounds, meaning that they evaporate quickly and release chemicals into the air. Essential oils are in many products: aromatherapy products, home fragrances, flavorings, personal care items (like shampoo), “natural” remedies, insect repellents, and so forth. Essential oils can sometimes be dangerous for pets, so be aware of the possible risks if you use these products. Whether an essential oil will cause a problem for an animal depends on the type of exposure, the concentration of oil, the animal’s individual risk factors, and the type of oil. The following essential oils are known to be toxic to cats and dogs, according to the Pet Poison Helpline.[1,2]
How Animals Are Exposed Essential oils enter the body through the skin, by swallowing, or by inhalation. Pets are most often exposed to toxic levels when owners apply an essential oil directly to the skin or fur in an attempt to treat a skin condition or repel fleas. The oil is absorbed into the body through the skin, and the animal is further exposed by licking oil from the fur. The risk increases with higher concentrations of essential oils. Products containing a high percentage of essential oil (approaching 100%) should never be applied directly to an animal’s skin or hair. Diffusers spread the fragrance of essential oils into a space. Passive diffusers work through evaporation: they send the scent of the oil, but not the oil itself, into the air. Passive diffusers are mainly a risk if a pet knocks one over and licks the oil or gets oil on the fur. Active diffusers (like nebulizers and ultrasonic diffusers) send actual particles of oil into the air. Oil from active diffusers can get onto an animal’s skin or be inhaled into the lungs, so the animal can have direct exposure to the oil without touching the diffuser. Strong odors from either type of diffuser can cause respiratory tract irritation. Animals at Risk Cats are at higher risk from essential oils than dogs are. Cats lack a liver enzyme that helps eliminate essential oils from the body. Cats and other animals that groom themselves are also more likely to swallow oil that’s collected on the fur. Animals with asthma or other respiratory problems are at higher risk than others from inhalation exposure from diffusers. Birds are very sensitive to respiratory irritants, so diffusers can also cause problems for them. Symptoms Depending on the type of oil and the amount of exposure, essential oil toxicity can cause vomiting, diarrhea, drooling, tremors, loss of balance, skin irritation, coughing, difficulty breathing, low heart rate, low body temperature, rear leg paralysis, and liver failure. Animals with symptoms of essential oil poisoning need veterinary care and might need to be hospitalized for intensive care. Using Essential Oils Safely Use essential oils with caution if you have pets. These tips can help keep your pets safe:

Abnormalities often show up on lab tests before an animal has obvious symptoms. Even healthy pets need to be tested regularly for parasites. Well-animal tests can detect problems early and help veterinarians track changes over time. These are some of the reasons your veterinarian might recommend lab tests for your pet:
Complete Blood Count A complete blood count measures the number, size, and shape of each type of cell in the blood.
Blood Chemistry Panel Blood chemistry tests measure substances in the blood that indicate changes in organ function or other biological processes. Blood chemistry analysis is run as a panel of many individual tests. A chemistry panel doesn’t always give a diagnosis for a sick animal, but the results can help the veterinarian narrow down the list of possibilities. Veterinary laboratories offer many chemistry panels for different species and diagnostic needs. A small panel that’s sufficient for a young animal before routine surgery might not be appropriate for an ill animal or an older pet. These are a few of the tests commonly included in chemistry panels:
Urinalysis Analysis of the urine includes specific gravity (a measure of urine concentration), pH, chemistry results like glucose and protein levels, and microscopic evaluation for cells, crystals, and bacteria. Urinalysis can reveal urinary tract infection, support a diagnosis of diabetes, and help evaluate the function of the kidneys and other organs. A complete laboratory analysis—especially for a senior pet—should include urinalysis. Parasite Tests Parasites are very common in pet animals (unless they have received regular parasite prevention as recommended by a veterinarian). Many of the parasites that pets carry are contagious to people. At least once a year, pets should have a stool test for intestinal parasites like hookworms and roundworms. Dogs should also have a yearly blood test for heartworm disease.

First aid can save an animal’s life, but it does not replace care at a veterinary hospital. Keep a first aid kit for your pets. Have contact information for animal poison control and nearby veterinary emergency clinics on hand. If possible, call the emergency clinic before you arrive with your pet. Handling an injured animal
Bee stings/insect bites If you can see the stinger in the animal’s skin, carefully remove it. Swelling of the face or throat that causes difficulty breathing is a medical emergency. Contact a veterinarian before giving any medication. Bleeding For external bleeding from a skin wound, apply gentle pressure with a gauze pad or clean cloth for at least a couple of minutes, until the blood clots. Do not use a tourniquet unless blood is spurting from a wound and the animal’s life is in danger (tourniquets can cause serious damage). Burns For thermal or electrical burns, remove the source of heat or electricity and apply cool compresses with a wet cloth. For chemical burns, flush the area with a large volume of water. Do not apply butter, ointment, or ice to the burn; seek veterinary care instead. Choking Coughing and reverse sneezing can be mistaken for choking. If the animal is truly choking on something in the throat, do a finger sweep of the mouth (only if you can do so without being bitten) and remove the object if possible. Be careful not to push the object farther down. If the animal collapses because of choking, try the Heimlich maneuver: lay the animal on its side and strike the rib cage a few times with the flat of your hand. Fractures In most cases you won’t know if your pet really has a fracture until a veterinarian has taken radiographs. Minimize your pet’s movement as much as possible during transport. Don’t give pain medication unless a veterinarian has specifically recommended it. Don’t try to splint the limb; the splint might make things worse and you could be bitten in the attempt. Heat stroke Heat stroke can happen quickly, especially if an animal is left in a car in warm weather. First aid should not delay immediate transport to a veterinary clinic. If you can’t transport the pet right away, move the pet into a cooler, shaded area. Apply towels soaked in cool water or pour cool water over the animal’s body, especially the neck, armpits, belly, and groin (between the back legs). Don’t use ice. Not breathing, no heartbeat Unfortunately, most animals with cardiac arrest die, even if they receive cardiopulmonary resuscitation. If you try resuscitation, it’s best to do it on the way to the veterinary clinic while someone else drives (no delay in transport). The first step is to check inside the mouth for an object blocking the airway. Then hold the mouth closed and breathe into the animal’s nose until the chest expands. Breathe every 4 to 6 seconds, checking after every few breaths to see if the animal can breathe on its own. After you have begun rescue breaths and if the animal still has no heartbeat, begin chest compressions. Lay the animal on its right side, place one hand under the ribs, and place the other hand on top of the ribs at the widest part of the rib cage (just behind the elbow). Push down on the ribs at least 1 inch, more for large dogs. For cats and other very small animals, cup the chest in one hand and squeeze the ribs between the thumb and fingers. Apply 80 to 120 compressions per minute for large dogs and 100 to 150 compressions per minute for cats and small dogs. Every 4 to 6 seconds, stop the chest compressions and give a breath. Continue until you have arrived at the clinic or the animal’s heart is beating and the animal is breathing. Poisoning If you think your pet has eaten or been exposed to a dangerous substance, call a veterinary clinic or an animal poison control hotline. Note the time of exposure, the amount you think your pet swallowed or was exposed to, and the symptoms. Keep the packaging material, if available, so the ingredients can be identified. If your pet vomits, take a sample of the vomit to the veterinary facility in case it’s needed for analysis. Don’t give anything to induce vomiting unless a veterinarian or animal poison control specialist has specifically recommended it. Seizure If possible, time the seizure and note what the animal did before, during, and after the convulsions (for example, acting “spaced out,” paddling the legs, or urinating). Keep your hands away from the animal’s face and don’t try to hold the animal. Move objects that could hurt the animal out of the way. If the animal is having a seizure near stairs, the edge of a deck, or another drop, use a physical barrier to keep the animal from falling. Snakebite Snakebites can be very painful, so use a muzzle to protect yourself from being bitten by your pet. Take a photo of the snake if possible, but stay away from it! Don’t try to catch or kill the snake. Keep your pet as calm as you can while you travel to the veterinary clinic. Don’t apply a tourniquet or ice, and don’t try to draw venom out of the wound.

Photo by Oscar Sutton on Unsplash Laurie Anne Walden, DVMPrepare for pet injuries and emergencies by collecting first aid supplies in advance. You can purchase a pet first aid kit or make your own. Some of the items in a family first aid kit can also be used for animals. Emergency clinic contact information Keep a list of phone numbers of emergency clinics in your area and at travel destinations. Include animal poison control phone numbers in your list. Emergency clinics can be very busy, so if possible have contact information for multiple clinics in case the nearest one has a long wait. Call the clinic before you arrive if your pet’s condition allows time for this. Vaccination records and medical history The most important vaccination record for an emergency clinic to have is the rabies vaccination. A list of current medications and medical conditions will also be helpful, especially if someone who is less familiar with your pet’s medical history (like a pet sitter) might be taking your pet for treatment. Your primary care veterinary clinic might be closed when your pet needs emergency treatment, so have written medical records available for the emergency service. Muzzle Animals in pain can bite even if they are friendly at other times. A muzzle will help you transport your dog safely. The best type of muzzle for a dog is a basket muzzle that allows the dog to pant. You can find inexpensive basket muzzles at pet stores and online. If you plan in advance, you can reduce your dog’s anxiety about using a muzzle during an emergency by training your dog to like wearing a muzzle. See the Muzzle Up Project for tips on muzzle training. (Short version: muzzles are treat baskets!) Don’t try to put a muzzle on a dog if you would be bitten in the attempt. Emergency muzzle alternatives include a leash, rope, necktie, or bandage material wrapped around the mouth. Items that hold the mouth completely closed should never cover the nostrils, should be used only for a very short time (just to get the animal into the car), and should not be used for animals that are vomiting. Another option is to cover the animal’s head with a towel or blanket, but take extra care—animals can bite through cloth, especially if they’re frightened or in pain. Leash or pet carrier A slip leash might be easier than a clip leash to put on a scared dog. For cats, consider keeping a hard plastic carrier with a top that can be removed. If you’ve picked up your cat with a towel, you can bundle both the cat and the towel into the bottom half of the carrier and then reattach the top half. Gauze sponges and nonstick pads Plain gauze squares are used to absorb blood and drainage but are uncomfortable if they stick to a wound. If you’re bandaging a wound, use a nonstick pad as the inner layer (touching the wound) and add layers of plain gauze over the nonstick pad as needed for absorption. Self-adherent bandage wrap (Vet Wrap or similar) Flexible self-adherent wrap is used as the outer layer of a bandage. This material bonds to itself but doesn’t stick to fur. It’s stretchy, so it can cut off circulation if it’s applied tightly. Don’t stretch it while you’re applying it; just lay it over the top of the gauze and press gently to adhere it to itself. Adhesive bandage tape If you have self-adherent wrap, you might not need adhesive bandage tape. Adhesive tape is used to hold a bandage together. For a first aid bandage, try to avoid sticking tape to the fur. If a pet needs a bandage that’s more secure than just self-adherent wrap over gauze, the pet needs to be seen at a veterinary clinic and someone there will be taking your bandage off anyway. Don’t use Band-Aids or other adhesive bandages meant for humans. Bandage scissors Antibacterial ointment Tweezers (for removing ticks) Disposable gloves Eye wash Eye wash or sterile saline is good to have on hand if a potentially damaging liquid gets splashed into an animal’s eyes. Use care when working around an injured animal’s face, though. Towels Towels are handy for mopping up messes, creating an impromptu stretcher, or soaking in water to cool an overheated animal. Medications and other remedies Medications like pain relievers and antihistamines should only be used if a veterinarian has specifically recommended them. Many pain relievers for humans, including common nonprescription pain relievers, are not safe for pets. Some pet first aid supply lists include products to induce vomiting or poison remedies like activated charcoal. Never use products like these without consulting a veterinarian first. Inducing vomiting can be harmful. For example, caustic substances and foreign objects can damage the esophagus on the way down and again on the way back up. Photo by Alvan Nee on Unsplash Laurie Anne Walden, DVMYeast skin infection (dermatitis) is common in dogs and also affects cats. Animals with allergies to pollen, grass, and other substances are especially prone to yeast dermatitis and yeast ear infections, so watch for the signs of infection if your pet gets itchy when the seasons change. Causes Yeast dermatitis is caused by Malassezia organisms on the skin. Malassezia yeasts are part of the normal collection of microorganisms that live on the skin and in the ears of animals. Yeast dermatitis occurs when something about the host animal—skin condition or immune function—causes Malassezia to overgrow or results in an abnormal immune response to Malassezia organisms. Examples of skin conditions that lead to yeast overgrowth are inflammation and increased moisture. Some animals are allergic to Malassezia and develop yeast dermatitis even when the number of organisms on the skin is relatively low. These are some of the things that increase the risk of yeast dermatitis:
Signs The most commonly affected areas are the face, neck, armpits, belly, inner thighs, feet, and ears, although yeast dermatitis can affect any part of the skin. Yeast dermatitis typically causes these signs:
Diagnosis Samples from affected areas are taken with various methods (tape pressed to the skin, a microscope slide pressed to the skin, cotton swabs, scraping with a blade, or possibly skin biopsy) and examined under a microscope. Animals with yeast dermatitis might have very few Malassezia organisms visible with a microscope. In animals with long-term or recurring yeast dermatitis, other tests are often done to look for an underlying cause. Treatment Yeast dermatitis is treated with topical medication, oral medication, or both. Topical antifungal products include shampoos, mousses, wipes, creams, and so forth. Topical products need enough skin contact time to be effective, so shampoos usually come with instructions not to rinse the lather off for at least 10 minutes. A number of prescription oral antifungal medications are also used. The choice of treatment type—topical, oral, or both—depends on the individual animal, the part of the body affected, the response to earlier treatment, and the ability of the animal’s owner to apply topical treatments. Not everyone has a place to bathe a large shaggy dog twice a week, for instance. Treatment for yeast dermatitis typically needs to continue for weeks. For animals with recurring yeast dermatitis, the underlying cause also needs to be treated. Reference 1. Bond R, Morris DO, Guillot J, et al.
