Cat Symptoms Checker
Choose what you have noticed for guidance on contacting a vet. This limited checklist cannot diagnose your cat, rule out an emergency, or replace an examination.
Difficulty breathing, collapse, seizures, inability to pass urine, suspected poisoning, major injury, uncontrolled bleeding, severe pain, or repeated severe vomiting need urgent veterinary help. Do not wait to complete this form.
Emergency guidance: Cornell’s emergency service and common cat hazards. The list is not exhaustive. If you are worried, call a veterinary clinic.
How to use this symptoms checklist
Start with the emergency signs shown above. If one is present, or you are unsure, the tool tells you to contact an emergency veterinarian now. Do not finish the form before seeking urgent help.
If none of the listed signs is present, select the change you have noticed and choose “Show next step.” Every non-emergency selection leads to advice to contact your clinic today. This checklist does not have a “safe to wait” result.
What this checker can tell you
It offers a simple route to veterinary contact, not a possible diagnosis. It does not compare diseases, assess severity from a photograph, calculate risk, or decide whether your cat needs treatment. Selecting “No signs from the list” cannot rule out an emergency.
Cornell’s emergency service identifies problems such as breathing difficulty, collapse, seizures, trouble urinating, severe pain, poisoning and serious injury as reasons for urgent attention. The warning list on this page is not exhaustive. If your cat seems seriously unwell, contact an emergency clinic rather than looking for a matching menu option.
What to tell the veterinary clinic
When you call, describe what you can observe. “Three trips to the litter box in ten minutes” gives the clinic a clearer starting point than “acting strange.” Do not delay an urgent call to collect every detail.
- When you first noticed the change and whether it is getting worse.
- What is different about eating, drinking, urination or stools.
- Your cat’s approximate age and known medical conditions.
- Current medicines and any possible exposure to a substance or object.
- Whether your cat is alert, moving normally and breathing comfortably.
As a practical note-taking format, use three headings: “What I saw,” “When it started,” and “What changed.” Record observations rather than naming a disease you suspect. The clinic can ask the follow-up questions needed for its assessment.
If you suspect poisoning
Contact a veterinarian promptly and identify the suspected product or substance if you can do so safely. Do not attempt to induce vomiting unless a veterinarian instructs you. Cornell’s guide to common cat hazards explains why home responses can create additional harm.
Frequently asked questions
Why does every concern recommend contacting a vet?
This tool collects too little information to judge that waiting is safe. It deliberately provides a contact step instead of a reassuring diagnosis or home-treatment plan.
What if my concern is not listed?
Choose “Something else / unsure” and contact your clinic. The available categories organize the form; they do not cover every possible problem.
Can I use it instead of an appointment?
No. A veterinarian may need an examination and additional information. The checklist cannot replace that assessment.
Will a vet receive my answers?
No. The tool works in your browser and does not send your entries to a clinic. You must make the call yourself.
Has this tool been reviewed by a veterinarian?
No. It is an educational checklist with linked veterinary sources, not a veterinary-reviewed diagnostic service.
