Do Cats Get Colds? What the Usual Answer Leaves Out

According to VCA Animal Hospitals, cats develop illnesses that resemble colds, although veterinarians classify them as feline upper respiratory infections, or URIs, usually involving feline herpesvirus type 1, feline calicivirus, or certain bacteria. VCA says their usual pathogens are species-specific even though human colds and feline URIs share sneezing and congestion. The Louisa County Animal Shelter sets more than 24 hours without food as a veterinary-contact threshold and lists panting or open-mouth breathing as reasons to call; PetMD defines feline fever as a temperature above 102.5°F.

The familiar answer, “Yes, cats get colds,” is useful only as a first sketch. It hides the questions that determine what happens next: which organism may be involved, whether the eyes or mouth are affected, whether the cat can smell and eat, how hard the cat is breathing, and whether an old herpesvirus infection has returned under stress. Those details reveal the condition under raking light.

Do cats get the same colds humans do?

Cats and people can both have viral infections in the upper respiratory tract. The Centers for Disease Control and Prevention defines a human common cold as a viral upper-respiratory infection that usually lasts less than a week; more than 200 respiratory viruses can cause one, with rhinoviruses the most frequent cause in the United States. Typical human signs include a runny or blocked nose, cough, sneezing, sore throat, headache, mild body aches, and sometimes a low-grade fever.

VCA uses “feline upper respiratory infection” as an umbrella term for disease caused by one or more feline viruses or bacteria. Its listed signs overlap with a human cold at the nose: sneezing, congestion, and nasal discharge. The feline pattern can also include conjunctivitis, eye discharge, squinting, oral ulcers, enlarged lymph nodes, poor appetite, lethargy, and fever. Those eye and mouth findings carry more diagnostic weight than the nickname “cold” suggests.

The comparison breaks at transmission. VCA says most organisms behind feline URIs are species-specific and pose no risk to people. It records rare exceptions, including Bordetella bronchiseptica illness in people with immune-system disease and isolated reports of Chlamydia felis-associated conjunctivitis in households with an affected cat. The CDC likewise separates a true human common cold from influenza, COVID-19, and respiratory syncytial virus, even though all can produce cold-like signs.

A household sneeze therefore does not establish who infected whom. VCA’s species-specific finding makes routine human-to-cat transmission of a common cold unlikely, while Cornell University’s feline respiratory guide notes that cats can acquire some influenza viruses from people. “Cold-like” describes appearance; it does not identify an organism.

What does a feline upper respiratory infection actually include?

VCA identifies feline herpesvirus type 1, also called feline viral rhinotracheitis, and feline calicivirus as the leading viral causes. Its clinical guide attributes approximately 90% of feline upper respiratory infections to those two viruses. Bordetella bronchiseptica and Chlamydia felis are among the better-known bacterial causes, with mycoplasma and feline reovirus listed less often.

The visible discharge is only the surface. VCA associates oral ulcers with herpesvirus and calicivirus, while the European Advisory Board on Cat Diseases describes dendritic corneal ulcers as a characteristic manifestation of feline herpesvirus. The ASPCA Shelter Medicine sample protocol says calicivirus is relatively likely with oral ulceration or limping, herpesvirus with eye trouble, and mycoplasma or C. felis with conjunctivitis. The same protocol cautions that signs overlap.

That overlap explains why a veterinarian may diagnose an uncomplicated URI from the examination without ordering a pathogen panel. The ASPCA protocol reserves diagnostic testing for unusual incidence, unusual severity, or failure to respond. VCA similarly says identification is not always necessary, although testing becomes more useful in breeding cats, poor treatment response, persistent disease, or suspected lung involvement.

Antibiotics do not treat the viral core of herpesvirus or calicivirus infection. The ASPCA sample protocol withholds antibiotics for mild cases with clear discharge and infrequent sneezing, then uses veterinary-directed antibiotics when findings support secondary bacterial disease. Colored discharge, dehydration, fever, coughing, reduced appetite, or deterioration change that decision; the color alone is still a reason for examination, not a home diagnosis of the organism.

How long does a cat cold take to appear and clear?

The timeline depends on the pathogen and on what “recovery” means. The European Advisory Board on Cat Diseases reports that clinical signs of feline herpesvirus usually appear two to six days after experimental infection, depending on viral dose, while acknowledging that incubation can be longer. It places resolution of acute herpesvirus disease at 10 to 14 days, with keratitis and other ocular disease capable of lasting longer.

VCA gives a broader two-to-10-day incubation range for feline URI as a group. It says an uncomplicated infection typically lasts seven to 14 days, although signs can persist for as long as 21 days. The ASPCA’s adopter and foster handout also places most uncomplicated cases within seven to 14 days when the cat receives supportive care in a calm setting. These ranges differ because one source describes named herpesvirus infection and the others describe a syndrome with several possible causes.

Visible recovery does not always mean elimination of the pathogen. Cornell’s Feline Health Center reports exposure to feline herpesvirus in up to 97% of cats and lifelong infection in up to 80% of exposed cats; as many as 45% of that infected group may shed virus periodically, usually during stress. The denominator matters. The 80% figure applies to exposed cats, rather than every cat in every population.

VCA uses similar language, estimating that approximately 80% of cats with feline viral rhinotracheitis become chronic carriers. The European Advisory Board goes further and says almost all cats after primary herpesvirus infection become lifelong latent carriers. These statements are not interchangeable population estimates: Cornell and VCA publish percentages, while the advisory board describes the biological outcome among confirmed primary infections.

How can an indoor cat get a cold?

An indoor cat can show a feline URI after a latent herpesvirus infection reactivates, after direct contact with an infected cat, or after contact with contaminated secretions on shared objects. VCA lists food and water bowls, litter boxes, toys, and bedding as possible fomites. Cornell identifies stress as a common trigger for periodic herpesvirus shedding, so a move, boarding stay, surgery, illness, or disruption at home may precede signs without a recent outdoor exposure.

The Koret Shelter Medicine Program at the University of California, Davis, ranks reactivation of latent herpesvirus under stress above aerosol spread in ordinary shelter URI control. Its guidance emphasizes droplets over short distances and contaminated hands, clothing, equipment, or housing. For a home with one long-established indoor cat, recurrence may fit the evidence better than an invisible airborne invasion from outdoors.

Vaccination changes expected severity more reliably than it guarantees zero infection. VCA says core vaccines against feline viral rhinotracheitis and calicivirus may reduce severity and shorten illness but cannot completely prevent infection after exposure. The ASPCA Shelter Medicine guide makes the same distinction for shelter cats: vaccination does not prevent every URI, viral shedding, or carrier state.

Which cat cold symptoms need veterinary care?

VCA lists sneezing, clear discharge, congestion, and mild lethargy among common URI findings, but its guide recommends more intensive care when dehydration, depression, or severe illness develops. Breathing effort outranks the neatness of any symptom list. VCA identifies difficulty breathing as a severe sign; the Louisa County Animal Shelter handout directs owners to contact a veterinarian for panting or open-mouth breathing.

Temperature needs a thermometer, according to PetMD veterinarians Tiffany Paul, DVM, and Barri J. Morrison, DVM. Their 2026 clinical review defines fever in a cat as a body temperature above 102.5°F. The Merck Veterinary Manual independently gives 100.5°F to 102.5°F as the normal feline rectal range. Warm ears, hiding, or poor grooming may accompany fever, but PetMD says touch cannot confirm it.

Food intake is another hard threshold. Louisa County Animal Shelter’s feline URI handout says to contact a veterinarian when a cat has eaten nothing for more than 24 hours. Cornell’s Feline Health Center explains why waiting is risky: anorexia can seriously affect a mature cat after as little as 24 hours, and a kitten younger than six weeks can face a lethal threat after 12 hours without food. Nasal blockage can suppress appetite because a cat cannot smell the meal; mouth ulcers can make each bite painful.

Veterinary contact is also warranted for green or yellow eye or nasal discharge, marked inactivity, dehydration, vomiting or diarrhea that persists, little improvement after a week of home care, or worsening at any point, according to the Louisa County handout. Eye pain deserves prompt attention. VCA includes squinting among URI signs, and the European Advisory Board links feline herpesvirus to corneal ulceration.

What cat cold home care is safe?

Home care suits a cat that is breathing comfortably, remains responsive, takes in food and water, and has no urgent eye problem. VCA and the ASPCA describe supportive care as the foundation for an uncomplicated viral URI. A veterinary examination remains appropriate when the cat is very young, elderly, pregnant, chronically ill, immunocompromised, or moving away from its normal pattern.

  1. Check danger signs before settling the cat. Count food intake, watch the chest and abdomen at rest, and look for open-mouth breathing, pronounced effort, collapse, dehydration, or a painful closed eye. VCA and Louisa County place breathing difficulty outside routine home care.
  2. Prepare a quiet recovery room. The ASPCA foster materials favor a calm, low-stress space with a hiding place. Keep the ill cat’s bowls, litter box, bedding, and toys separate from those used by unaffected cats.
  3. Clear the nose and eyes gently. VCA recommends wiping discharge with a moist tissue. For congestion, its clinical guide suggests a steamy bathroom for 10 to 15 minutes several times a day; the cat should stay away from hot water and any direct steam source.
  4. Offer aromatic food and record intake. VCA recommends palatable canned food because congestion reduces smell. The Louisa County handout suggests warming wet food to strengthen its aroma. Record meals, drinking, urination, discharge, energy, and medication so a veterinarian can see the trend rather than a single snapshot.

Human cold remedies do not belong in this procedure. The U.S. Food and Drug Administration advises against giving medicine intended for people or another animal unless a veterinarian directs it, and specifically states that acetaminophen is fatal to cats. Antibiotics, eye preparations, decongestants, appetite stimulants, and antiviral drugs require a feline diagnosis and veterinary dosing.

How long should a cat with respiratory signs be separated?

Separation has two clocks: observation after arrival and contagiousness during illness. The Louisa County Animal Shelter protocol recommends isolating every newly adopted cat from resident cats for seven to 10 days, allowing time for signs to emerge after the stress of relocation. VCA recommends at least one to two weeks for a new cat and a veterinary examination before contact with resident cats.

An actively ill cat can remain infectious longer. VCA Animal Hospitals veterinarians Malcolm Weir, DVM, MSc, MPH, and Cheryl Yuill, DVM, MSc, CVH, write, “A cat with an acute upper respiratory infection will be infective to other cats during the incubation period and for up to three weeks after developing symptoms.” VCA also notes that a chronic carrier may remain intermittently infectious.

Shelter protocols do not all impose one fixed isolation period. The ASPCA’s 2026 foster-kitten URI protocol permits kittens treated for at least five to seven days to proceed to surgery or adoption after at least two days without clinical signs. Its broader shelter protocol calls for designated isolation housing during treatment, yet allows mild cases to remain in place when trained staff can prevent transmission and avoid the stress of moving. A household release date therefore belongs to the treating veterinarian, especially around kittens, unvaccinated cats, or medically fragile cats.

During separation, VCA recommends dedicated supplies and thorough handwashing before and after handling another cat. The ASPCA shelter protocol advises care of healthy cats before URI patients. These measures address direct contact, droplets, and fomites while preserving a quieter room for recovery.

Why can a cat cold return after recovery?

Feline herpesvirus changes the meaning of “recovered.” Cornell says the virus can establish lifelong infection, become inactive, and later reactivate during stress. The cat may look entirely well between episodes. Recurring eye discharge or sneezing therefore may represent recrudescence of an existing infection rather than a newly caught illness.

Persistent or repeated signs still need reassessment. VCA recommends additional diagnostics for long-lasting or recurring symptoms, which may include imaging, blood tests, or culture depending on the examination. The ASPCA protocol flags chronic, treatment-resistant URI for investigation of other contributors such as an oropharyngeal polyp, retroviral infection, or dental disease.

Recovery should be judged by function and trend: comfortable breathing, normal interest in food, improving eyes and nose, usual activity, and sustained absence of signs before reintroduction. A glossy “seems better” impression can hide a cat that still cannot smell dinner or has begun to squint. Appetite, breathing, and eye comfort are the revealing light.

Frequently asked questions

Can indoor cats get colds?

Yes. VCA says indoor cats can develop feline upper respiratory infections through contact with an infected cat or contaminated bowls, bedding, toys, and litter boxes. Cornell adds that latent feline herpesvirus can reactivate during stress, so symptoms may appear without a recent outdoor trip or a clearly sick visitor.

How long do cat colds last?

VCA says an uncomplicated feline upper respiratory infection usually lasts seven to 14 days, although signs can continue for up to 21 days. The European Advisory Board on Cat Diseases gives 10 to 14 days for acute feline herpesvirus disease and warns that eye complications or chronic disease can last longer.

Can cats catch colds from humans?

VCA says the usual feline URI pathogens are species-specific, making transmission of an ordinary human cold to a cat unlikely. Cornell notes a narrower exception: cats can contract some influenza viruses from people. The CDC classifies influenza separately from the common cold, despite the overlap in respiratory symptoms.

What can I give my cat for a cold?

VCA recommends supportive measures such as palatable canned food, gentle cleaning of eye or nose discharge, and humidification for uncomplicated cases. Medication requires veterinary direction. The FDA says acetaminophen is fatal to cats and advises against giving human or another animal’s medicine unless a veterinarian specifically directs its use.

When should I take my cat to the vet for a cold?

Louisa County Animal Shelter advises veterinary contact after more than 24 hours without food, with colored discharge, marked depression, breathing difficulty, or little improvement after a week. PetMD defines feline fever as above 102.5°F. Open-mouth or labored breathing, collapse, dehydration, or a painful eye warrants prompt assessment.

Can a vaccinated cat still get a cold?

Yes. VCA says vaccines against feline herpesvirus and calicivirus do not completely prevent infection after exposure, although they can reduce severity and shorten illness. The ASPCA adds that vaccination does not eliminate viral shedding or the carrier state. A vaccinated cat with breathing trouble, poor appetite, fever, or eye pain still needs assessment.
