Most cats with COVID-19 recover on their own within 7 to 15 days with basic home care. The virus typically causes mild respiratory symptoms in cats, and treatment focuses on keeping your cat comfortable, isolated, and well-hydrated while their immune system clears the infection. There are no approved antiviral treatments specifically for feline COVID-19, so supportive care is the standard approach.
What COVID-19 Looks Like in Cats
The most common signs are sneezing (about 40% of symptomatic cats) and lethargy (around 38%). Your cat may also lose interest in food, develop a runny nose or watery eyes, or cough occasionally. Digestive symptoms like diarrhea and vomiting are less common, showing up in only about 6% of cases. Some cats run a mild fever.
Many infected cats show no symptoms at all. Among those that do get sick, the illness is primarily respiratory and mild. In a systematic review of documented feline cases, more serious complications like heart inflammation were reported in a subset of animals, though researchers couldn’t confirm those were directly caused by the virus rather than pre-existing conditions.
Home Care Basics
Your veterinarian will likely recommend home isolation if your cat is stable, you can safely provide care, and you have a separate room where the cat won’t share space with other people or pets. Here’s what that looks like in practice:
- Isolate your cat in one room. Keep them away from other household members and pets. Do not let them roam outside.
- Encourage eating and drinking. Offer fresh water frequently. If your cat is turning down dry food, try warming up wet food slightly to make it more appealing. A cat that hasn’t eaten for more than 24 hours needs veterinary attention.
- Keep the room warm and quiet. A comfortable, low-stress environment supports recovery. Make sure litter, food, and water are all within easy reach.
- Protect yourself during care. Follow the same precautions you’d use when caring for a person with COVID at home: wash your hands before and after handling your cat, and avoid close facial contact like snuggling or letting them lick you.
There’s no cat-specific COVID-19 medication your vet will prescribe. While antiviral compounds like GS-441524 and remdesivir have proven effective against feline infectious peritonitis (FIP), a different and more serious coronavirus disease in cats, these drugs are not standard treatment for SARS-CoV-2 infections in cats. Your vet may provide supportive treatments if symptoms are more pronounced, such as fluids for dehydration or medications to reduce fever.
When Symptoms Need Urgent Attention
Watch your cat’s breathing closely. A healthy resting cat breathes 10 to 25 times per minute. You can count this by watching their chest rise and fall while they sleep. If the rate climbs above 30 breaths per minute, or if you notice your cat breathing with an open mouth, visibly straining with each breath, or showing exaggerated belly movements while breathing, that signals possible fluid buildup in the lungs or serious respiratory distress.
Other red flags include complete refusal to eat or drink for more than a day, extreme lethargy where your cat is unresponsive to stimulation, or any sudden neurological changes like pressing their head against walls or losing coordination. These situations call for immediate veterinary care. If you need to transport a sick cat, call the clinic ahead so they can prepare an isolation area and appropriate protective equipment.
How Long to Keep Your Cat Isolated
CDC guidance says your cat can return to normal activities when two conditions are met: the cat has been symptom-free for at least 72 hours without any medical treatment, and either 14 days have passed since the last positive test or follow-up testing comes back negative. Until then, keep your cat indoors and away from other animals and people outside your household.
For most cats, this means roughly two to three weeks of restricted activity from the point of diagnosis. If your cat was only mildly symptomatic, you’ll likely see improvement within the first week, but the full isolation period is important to prevent spreading the virus to other pets or, in rare cases, back to humans.
Cleaning and Disinfection Around Your Cat
SARS-CoV-2 is an enveloped virus, which means it’s relatively easy to destroy on surfaces. But you need to choose cleaning products carefully because cats are unusually sensitive to many common disinfectants.
The safest and most effective approach is heat. Wash bedding, blankets, and fabric items at 60°C (140°F) or higher. For hard surfaces like floors and food bowls, a diluted bleach solution (sodium hypochlorite) works well, but you must rinse surfaces thoroughly afterward and ventilate the room. Bleach releases chlorine gas that irritates airways, which is the last thing a cat with respiratory symptoms needs.
Two categories of cleaners to avoid entirely around cats: phenol-based products (including many essential oil cleaners, particularly those containing pine or tea tree oil) and quaternary ammonium compounds like benzalkonium chloride, which are toxic to cats and also poor performers against many viruses. Always clean surfaces of visible debris before applying any disinfectant, since organic matter blocks the chemical from reaching the virus.
Protecting Other Pets in Your Home
Cats appear more susceptible to SARS-CoV-2 than dogs, so if you have multiple cats, strict separation matters. The infected cat should have its own litter box, food and water dishes, and bedding. Don’t share toys between animals during the isolation period. Wash your hands and change clothes if possible after spending time in the sick cat’s room before interacting with your other pets.
If you’re the one who brought COVID into the household in the first place, limit contact with all your pets while you’re symptomatic. That means no petting, no sharing your bed, and no letting them lick your face or hands. The most common route of infection for household cats is direct contact with a sick owner.
