Cat Symptom Checker

Not sure how worried to be? Pick what you are seeing in your cat and get likely causes, a general sense of how urgent it is, and the guide that covers it. This is educational triage to help you decide your next step, not a diagnosis.

This is not a diagnosis. This checker gives general, educational guidance to help you decide how urgent a symptom is and which guide to read next. It cannot examine your cat or replace a veterinarian. If your cat is unwell or you are worried, contact your vet.

How to Read Your Cat's Symptoms

Cats are experts at hiding illness, so the most useful signal is a change from your cat's normal. A cat that suddenly eats less, drinks more, hides, stops using the litter box, or loses weight is telling you something. Note when it started, what else changed, and whether the symptom is getting better or worse. A short phone video of an episode, such as a cough or a straining trip to the box, helps your vet enormously.

Symptoms rarely appear alone, and a cluster is often more informative than any single sign. Use this checker for each thing you are noticing, then bring the full picture to your vet. For a broader overview, start with our sick cat symptoms guide, or browse every topic in the Cat Health guides.

Why This Is Not a Diagnosis

A symptom can have many causes, and only a veterinarian can examine your cat, run tests, and tell you what is actually going on. This tool cannot feel your cat's belly, listen to their chest, or check their bloodwork. What it can do is help you gauge urgency and point you to the right reading, so you know whether to monitor at home, book a visit, or go to an emergency clinic now. When in doubt, a quick call to your clinic is always the safest next step.

Many health problems in cats show up first as a change in weight or body condition. To track that at home, use our Cat BMI Calculator and the cat weight guides.

FAQs

Frequently Asked Questions

Can this cat symptom checker diagnose my cat?

No. This tool is for general information only and cannot diagnose your cat. It helps you understand what a symptom might mean, how urgent it usually is, and which guide to read next. Only a veterinarian can examine your cat, run tests, and give a diagnosis. If you are worried, contact your vet.

How do I use the cat symptom checker?

Select the symptom you are noticing, such as vomiting, straining in the litter box, drinking a lot of water, or losing weight. The checker shows likely causes to discuss with your vet, a general urgency level, and a link to the guide that covers that symptom in detail. Always read the emergency red flags at the top first.

What cat symptoms are an emergency?

Treat it as an emergency and seek veterinary care right away for open-mouth or labored breathing, a male cat straining with little or no urine, blue, grey, or very pale gums, collapse or a seizure, repeated vomiting with inability to keep water down, a hard painful belly, or not eating at all for more than 24 hours. These cannot wait for a routine appointment.

My cat has more than one symptom. What should I do?

Symptoms often cluster, and a combination can be more meaningful than any single sign. For example, increased thirst with weight loss points somewhere different than vomiting with diarrhea. Check each symptom here, note when everything started, and share the full picture with your vet, who can connect the signs.

When should I call the vet even if my cat seems okay?

Cats hide illness well, so a lasting change from your cat's normal is reason enough to call, even without an obvious emergency. Increased thirst, gradual weight loss, eating less, hiding, or changes in litter box habits are all worth a vet conversation, because catching problems early usually makes them easier to manage.
