Cat Health & Symptoms: Is My Cat Sick?

Plain-English cat health answers to the worrying stuff — what’s normal, what’s not, and exactly when it’s time to call the vet. Researched carefully, written by real cat people.

Quick answer:

Most sudden changes in a cat (appetite, litter-box habits, energy) are worth watching closely for 24–48 hours. Use the guides below to tell everyday quirks from genuine red flags, and never wait on breathing trouble, a male cat straining to pee, repeated vomiting, or a cat that hasn’t eaten in a day.

When to stop reading and call your vet

Most changes can be watched for a day or two. These can’t — call your vet (or an emergency clinic after hours) straight away if your cat has:

Trouble breathing, or breathing with an open mouth
A male cat straining to pee, or peeing little or nothing — this can be a blockage
Repeated vomiting, or vomiting with lethargy
Not eaten anything in 24 hours
Pale, white or blue-tinged gums
Suspected poisoning — lilies, antifreeze or human medicines
Collapse, a seizure, or sudden weakness in the back legs

Not sure if it’s urgent?

If in doubt, call. Your vet would always rather hear from you early.
