No. Brownies are concentrated chocolate — treat any eaten piece as an emergency.

Why it’s a problem

Brownies pack cocoa into a dense, fudgy base, so a small square can deliver a meaningful theobromine dose to a cat. Sugar, butter and sometimes nuts or xylitol-based sweeteners pile additional risks onto an already toxic treat.

How to serve it safely

Keep brownies and brownie mixes stored away — cocoa powder in the mix is even more concentrated — and clean crumbs promptly.

Warning signs to watch for

Vomiting, diarrhea, restlessness, rapid breathing, muscle tremors, racing heart and seizures, typically within 6 to 12 hours.

When to call the vet

Contact a vet or pet poison hotline immediately after any brownie exposure — treatment works best before symptoms start.

Common questions

My cat only got a corner piece — is it still serious?

Corner or not, chocolate content in brownies is meaningful for a cat’s weight. Call your vet with the estimated amount and type.
