What should I do if my cat ate Cannabis?

Move the cat to a quiet, low-light room and minimize handling — they are acutely sensitive to noise, light, and touch while intoxicated. Block access to any remaining product. Do not induce vomiting at home; that decision belongs to the vet, and bringing the actual product or label helps them estimate the THC dose. Call immediately for any seizure, severe agitation, collapse, or suspected ingestion of a concentrated product (edible, THC oil, vape cartridge), and for any worsening past the first hour. For mild wobbliness, call your vet or Pet Poison Helpline (855-764-7661) right away — vomiting is most useful within 30 to 60 minutes of ingestion, so timing matters.

What should I do if my dog ate Cannabis?

Settle the dog somewhere padded where they cannot fall down stairs or off furniture, and keep the room quiet — bright light and noise worsen the agitation. Pull any remaining product out of reach and bring the wrapper or label to the vet so they can estimate the dose. Do not induce vomiting at home unless the vet specifically tells you to. Call immediately for any seizure, collapse, severe agitation, or any ingestion of a concentrated product (THC oil, baked edibles, butter, vape cartridge). For mild wobbliness, call your vet or Pet Poison Helpline (855-764-7661) right away — they can decide whether to induce vomiting, which is most useful in the first 30 to 60 minutes after ingestion.
