Is Marijuana Edibles & THC Products Safe for Cats?
Why it’s a problem
Cats are more likely than dogs to be poisoned by licking cannabis-infused oils, melted butter, or a bitten gummy left on a table, and their small size means tiny amounts matter. THC affects a cat’s nervous system and heart, producing hours of disorientation, wobbliness, and abnormal heart rate. Edibles can also contain chocolate or other ingredients toxic to cats, stacking one poison on another.
How to keep your pet safe
Store all products, including oils and baked goods, in closed cabinets or lockboxes — cats walk counters and table surfaces freely. Never leave butter, oil, or gummies unattended on counters, and clean any spill with soap and water so paws and fur stay clean. Remind guests not to leave purses or snacks out.
Warning signs to watch for
Wobbliness, dilated pupils, glassy eyes, drooling, vomiting, agitation or unusual drowsiness, low body temperature, slow heart rate, tremors, disorientation (often starts within 30–60 minutes and can last many hours).
When to call the vet
Call your veterinarian or a pet poison hotline immediately and describe exactly what and how much was eaten — accurate information guides care, and honesty will not get you in trouble. Bring the packaging if you can. Do not attempt home remedies or wait out severe signs.
Common questions
My cat licked cannabis oil off the counter — is that dangerous?
Yes, concentrated oils can poison a cat even in small licks. Call your veterinarian or a pet poison hotline now and monitor for wobbliness, dilated pupils, or unusual drowsiness.
My cat ate a piece of a marijuana brownie — what now?
Call your veterinarian or a pet poison hotline immediately. Besides THC, brownies contain chocolate and fat that harm cats, so the vet needs the full picture.
Do cats get high from secondhand smoke?
Cats can absorb THC from heavy smoke in closed rooms, though swallowing products is far more dangerous. Keep the room ventilated and the cat out while using, and store all products away.
