No. THC is toxic to cats, and edibles are doubly dangerous because of their other ingredients.

Why it’s a problem

Cats are sensitive to THC and develop neurological signs from doses that seem small. Edibles are the most common route — brownies and gummies add chocolate, xylitol or raisins to the problem — and secondhand smoke in a closed room can also affect a cat.

How to serve it safely

Store flower, edibles and vape products in sealed containers out of reach, and ventilate thoroughly if you smoke indoors.

Warning signs to watch for

Wobbliness, dilated pupils, drooling, vomiting, urinary leakage, slow heart rate and deep lethargy, starting within an hour or so.

When to call the vet

Take a cat to a vet after any known ingestion — vets are focused on treatment, not judgment, and full honesty speeds diagnosis.

Common questions

What about CBD products?

Pet CBD products with negligible THC are a different substance, but quality varies wildly. Ask your vet before using any of them.
