Cat symptom photo checker
Seen something odd on your cat, or in the litter box? Our cat symptom photo checker matches your photo to common visible problems, from cat skin problems and cat eye discharge to red gums in cats, vomit and stool. It tells you how urgent it usually is and which guide to read. It is not a diagnosis.

Photograph what you’re seeing
If your cat is struggling to breathe, has collapsed or is bleeding heavily, don’t scan. Go to a vet now.
- Get close to the skin, eye or mouth, or to what’s in the litter box
- Use bright, even light
- Take a few and use the sharpest one
Photos are checked, then deleted. We never store them.
Get close to the skin, eye or mouth, or to what’s in the litter box
Is the photo clear?
Sharp and well lit works best. If it’s blurry or too dark, take another.
Looking at your photo…
Matching it to 16 common visible problems.
This isn’t a diagnosis. A photo can’t show how your cat feels or what’s causing a problem; only a vet can tell you that. Not sure how urgent it is? Check the signs.
How the symptom photo check works
- Take or upload a photo. Get close to the problem in good light. Don’t upset or restrain a cat in pain to get a photo.
- We match it to our categories. The scanner only chooses from the problems listed below, and flags if blood is visible or it looks severe.
- You see our advice. How urgent it is, when to go now and which guide to read all come from our own guides, not from the AI.
A photo can’t show everything. If you’re unsure, answer a few questions in our Should I go to the vet? checker.

Symptom photo checker questions
Can a cat symptom photo checker diagnose my cat?
No. A photo can show what a problem looks like, such as a rash or eye discharge, but not what’s causing it or how your cat feels. Use the result to decide how soon to call your vet, not as a diagnosis.
When is eye discharge in cats an emergency?
Go the same day if your cat is squinting or holding an eye shut, the eye looks cloudy or injured, or a kitten’s eyes are crusted shut. Watery cat eye discharge with sneezing is often a cat cold and can usually wait for a normal appointment.
What do red gums in cats mean?
A red line along the gums is usually gingivitis, an early sign of dental disease. Pale, white, blue or yellow gums are different: they can mean a serious problem, so go to a vet now.
