What to Tell Your Vet About Your Cat's Symptoms
A practical checklist for describing cat symptoms to your vet: appetite, litter box, hiding, breathing, and what to bring.
Short answer
Tell your vet what you are seeing, when it started, whether it is better or worse, and what else changed: appetite, water, litter-box habits, energy, hiding, and breathing. Cats mask illness — specific notes beat “she seems off.”
Exam-room amnesia is worse with cats because many signs happen when you are not watching. Walking in with a short timeline and litter-box observations often shortens the path to a useful plan.
What to tell your vet about your cat's symptoms
Start with identity and baseline context:
- Age, breed or type, weight trend if you know it
- Indoor, outdoor, or both; other pets in the home
- Current medications, diets, and known conditions
- Recent stress: movers, new pets, boarding, litter changes
Describe each symptom clearly
What exactly you saw
“Vomited foam twice after midnight” is better than “upset stomach.”
When it started
Sudden overnight vs gradual over days.
Appetite and water
Last confirmed meal time matters a lot in cats.
Litter box
Urine clumps, stool quality, straining, going outside the box.
Cat details owners often forget
- Hiding more, clinging more, or sleeping in new places
- Breathing rate at rest, open-mouth breathing, or belly effort
- Gum or eye color changes, drooling, pawing at the mouth
- Access to plants, strings, human medication, or essential oils
If appetite loss is the main issue, pair this checklist with cat not eating: when to worry.
Bring these with you
- Phone videos of breathing, limping, or litter-box straining
- A list of food brands and any recent switches
- Medication names and doses
- A fresh stool sample if the clinic asked for one
