πŸ“ Summary

Cat flu (feline herpes/calicivirus) is mild in early stages β€” good food, warmth, and cleaning clear it β€” but late-stage signs like pus, eye cloudiness, and appetite loss need medication. Catch it early and most cats recover well at home.

1 How Serious Is Cat Flu?

Can cat flu be fatal?

It used to be, but with today’s know-how most owners manage it β€” whether to see a vet or treat at home is your call. Capable owners handle it themselves; uncertain ones go to the clinic. Raising a cat is like raising a child: it forces you to learn.

Stages of cat flu:

(1) Early: runny nose, sneezing, eye discharge; some get diarrhea or bad breath. When mild, appetite and play are unaffected and it’s easy to miss. An owner can handle this stage well β€” tasty food, a calm warm space, warmth, cleaning eye discharge, and supplements bring quick recovery. Early cat flu is not serious.

(2) Late: pus-like nasal discharge, tearing, cloudy eyes, conjunctivitis or ulcerative keratitis, ongoing sneeze and cough, poor appetite, low spirits. This stage needs medication β€” vet or home, your choice. Standard care: antivirals, antibiotics, eye/nose discharge treatment, rehydration, energy support, plus the early-stage hands-on care.

Act at the first sniffle β€” early care keeps cat flu from progressing.
