Can cats catch SARS‑CoV‑2 from people?
Yes, cats can become infected with SARS‑CoV‑2, the virus that causes COVID‑19, and the predominant route is from humans to cats. Multiple studies and public‑health reports document household transmission in which a person with COVID‑19 spreads the virus to one or more cats. Cats are susceptible to infection and can develop mild respiratory signs, though many remain asymptomatic. As of 2024, there is no evidence that cats play a significant role in spreading the virus back to humans, and routine public‑health guidance focuses on reducing cat infections by protecting people with COVID‑19.
How transmission between cats and people occurs
Transmission most often happens through close contact with respiratory secretions and aerosols from an infected person. Activities that increase risk include coughing, sneezing, sharing close indoor spaces, and handling a cat without basic precautions. Because cats groom themselves and explore with their mouths and noses, virus particles on hands, clothing, or shared items can easily enter their respiratory or oral mucosa. The cat’s own susceptibility depends on viral dose, individual immune status, and prior exposure or vaccination. Cats are not a driver of the pandemic, but they can become infected in household settings where human cases are present.
Reported routes of human-to-cat transmission
- Direct contact with respiratory droplets or aerosols from coughing or sneezing.
- Contact with saliva, nasal, or ocular fluids from an infected person.
- Sharing contaminated environments, such as unventilated rooms, and shared bedding or food bowls.
- Indirect transfer via hands, clothing, or surfaces that have viral particles.
What illness looks like in cats
When cats do become symptomatic, illness is usually mild and short-lived. Signs can include fever, lethargy, sneezing, nasal discharge, coughing, eye discharge, and occasionally vomiting or diarrhea. Serious disease is uncommon, and fatalities are rare. Many infections are subclinical, meaning the cat shows no obvious signs yet can still shed virus for a limited time. If you notice persistent respiratory signs or fever, contact your veterinarian for guidance and possible testing.

Reducing the risk of cats catching COVID‑19 from people
Risk can be lowered with simple, practical measures that align with everyday hygiene and household routines. If someone in your home has COVID‑19 or is awaiting test results, a few targeted steps help protect cats. These strategies are grounded in how the virus spreads and how cats interact with their environment. They also support overall respiratory health for both people and pets.
Practical steps to protect cats
- Isolate people with COVID‑19 from pets when possible; use separate rooms and, if feasible, a separate bathroom.
- Wear a well‑fitting mask when in shared spaces to reduce aerosol spread.
- Wash hands before and after handling cats, feeding, and cleaning litter or food areas.
- Avoid close contact such as kissing, hugging, or letting a cat sleep on your face while symptomatic.
- Clean and disinfect high‑touch surfaces regularly; launder bedding and soft toys as appropriate.
- If you are sick, have another household member care for the cat’s feeding, grooming, and litter needs.
Vaccination, testing, and veterinary guidance
As of 2024, available COVID‑19 vaccines for cats are not widely used in many regions and are generally considered optional rather than core. Decisions about vaccination should be made together with your veterinarian, taking into account your cat’s lifestyle, local virus circulation, and your household risk. If a human case is identified at home, contact your veterinary clinic for advice on testing and monitoring. Your veterinarian may recommend testing if your cat shows respiratory signs and there has been known exposure. There is no evidence that cats transmit SARS‑CoV‑2 to humans under typical household conditions, but prudent precautions are reasonable.
When to test and seek veterinary care
Testing is generally considered when a cat has respiratory signs and there has been known exposure to a person with COVID‑19. Many veterinary labs can process nasal or oral swabs, and some public‑health veterinary partnerships may offer guidance on sample submission. Mild signs often resolve without specific antiviral treatment, but your veterinarian can advise on supportive care, monitoring, and when to seek care. If breathing becomes difficult, if fever is persistent, or if the cat is very young, very old, or immunocompromised, seek prompt veterinary attention.
Context and long‑term considerations
Cats have been infected with SARS‑CoV‑2 in household and shelter settings, and research continues to evaluate variants, vaccine options, and long‑term immune responses. While cats can be infected, they are not a reservoir that drives human community spread. Public‑health guidance continues to emphasize protecting people as the primary way to reduce cat risk. Staying up to date with human vaccinations, improving indoor ventilation, and practicing basic hygiene reduce opportunities for both human and animal infection. These measures help maintain trust in the human–animal bond while protecting health on both sides.
Bottom line
Cats can become infected with SARS‑CoV‑2 when exposed to people with COVID‑19, most often catching the virus through close contact and respiratory droplets. Illness in cats is usually mild or absent, and there is no evidence that cats significantly spread the virus to people. The most effective way to lower a cat’s risk is for symptomatic or infected people to minimize close contact and follow standard respiratory hygiene and hand‑washing practices. If you think your cat may have been exposed or is showing signs, reach out to your veterinarian for tailored advice.
