Sneezing, runny nose, and eye discharge in cats often signal a viral respiratory infection. In kittens or immunocompromised cats, what seems like a simple cold can escalate quickly.
Rapid, repeated sneezing is one of the first signs of feline herpesvirus or calicivirus infection.
Starts clear and watery; turns yellow or green if a secondary bacterial infection develops.
Conjunctivitis often accompanies URI. In severe cases, eyes may be crusted shut.
Body temperature above 39.5°C (103°F), combined with reduced energy and appetite loss.
Characteristic of calicivirus. Oral pain may prevent the cat from eating.
Nasal congestion can force mouth breathing. In kittens, this can progress to pneumonia.
Cat 'colds' are most commonly caused by feline herpesvirus (FHV-1) and feline calicivirus (FCV). Both spread through sneezing and direct contact, making multi-cat environments particularly vulnerable.
Once infected with herpesvirus, a cat carries it for life. The virus remains dormant until stress or illness triggers a flare-up — similar to cold sores in humans. Managing stress is a key part of long-term care.
Vaccination (FVRCP — the standard 3-in-1 or 5-in-1 vaccine) significantly reduces the severity of infection. Even strictly indoor cats can be exposed through contact with clothing or shoes that have come from outside.
CatsMe helps you track respiratory symptoms across all cats in your household — critical for managing infections in multi-cat homes. Log sneezing frequency, eye discharge, and appetite daily to catch flare-ups early.
Get Started FreeNo. Feline herpesvirus and calicivirus are cat-specific and do not infect humans. However, between cats, these viruses are highly contagious — isolate a sick cat and wash your hands thoroughly to protect others in the household.
Symptoms typically improve within 1–3 weeks. However, the herpesvirus itself remains in the body permanently and can recur. Veterinary care (antiviral eye drops, antibiotics for secondary infections) speeds recovery and prevents complications.
A congested nose means your cat can't smell food, which kills appetite. Try warming wet food slightly to intensify the aroma, wiping discharge from the nose, or offering strongly-scented foods. If your cat hasn't eaten for 24 hours, see a vet.
