Why

The ASPCA lists cannabis as toxic to cats with the same signs. Tell the vet exactly what was eaten and how much — they need the facts to treat, not to judge.

Signs to watch for if your cat has eaten marijuana and thc edibles

Signs can lag by a day or more, so no symptoms does not mean your cat is clear — call rather than watch.

What to do now

Call your vet or the ASPCA Animal Poison Control Center at (888) 426-4435 straight away. Tell them what your cat ate, roughly how much, and when, and take the packaging with you. Don't wait for symptoms — with several poisons the harm is done before a pet looks ill.

Never induce vomiting and never give any medicine unless a vet tells you to — it can do more damage than the poison. What we will and won't tell you.
