No. Cats are highly sensitive to trazodone, and unsupervised ingestion can cause severe sedation or serotonin toxicity — treat it as urgent.

Why it’s a problem

Trazodone is used in cats by some veterinarians, but cat doses are extremely small and the margin is narrow. Cats exposed to human tablets have been reported to show deep sedation, paradoxical panic, or serotonin syndrome with fever and tremors. A single human tablet may represent many cat doses.

How to keep your pet safe

Store trazodone where a cat cannot paw a bottle off a shelf or counter. If your cat stresses during travel or clinic visits, ask your veterinarian for cat-appropriate sedation advice rather than sharing pills.

Warning signs to watch for

Profound drowsiness, wobbliness, dilated pupils, vomiting, drooling; paradoxical agitation or vocalizing; serotonin toxicity: tremors, rapid breathing, fast heart rate, fever, seizures.

When to call the vet

Call your veterinarian or a pet poison hotline promptly with the tablet strength and the number possibly eaten. Do not give anything else at home and do not wait for symptoms in a small cat.

Common questions

My cat licked a trazodone tablet — is that a problem?

Possibly — cat doses are tiny, so even partial ingestion matters. Call your vet or a pet poison hotline for guidance based on your cat’s weight and the amount involved.

Is trazodone ever used for cats?

Yes, some veterinarians prescribe it at very small doses for travel or exam stress, but only under veterinary direction. Never share your own tablets.
