What is a cat symptom checker?

A cat symptom checker is a tool that asks about your cat's symptoms and tells you how urgent they are and what to do next. Omelo's free cat symptom checker routes each case through 500+ vet-authored decision pathways, flags red-flag emergencies, and gives a clear next step in about 30 seconds, personalized to your cat's age and history.

Is Omelo's cat symptom checker free?

Yes. It is free, with no sign-up, no card, and no trial timer. Urgent triage is never limited. The free app also includes the dog symptom checker, daily health logging, a vaccination tracker, and breed-specific guides.

When is a cat symptom an emergency?

Cats hide illness by instinct, so subtle changes matter more than they would in a dog. A cat that has not eaten for 24 or more hours is a serious risk for hepatic lipidosis (fatty liver) and should see a vet. Go to a vet now for labored or open-mouth breathing, straining in the litter box with no urine, collapse, or suspected poisoning.
