Verdict

Edibles are the usual problem: a brownie or gummy on the floor. Cats show dilated pupils, wobbliness, lethargy, and sometimes vomiting or urinary accidents. Chocolate in the edible adds a second toxin. CBD oils may still contain THC, flavorings, or xylitol. This page is not permission to “microdose” a cat.

Symptoms to watch for

  • • lethargy
  • • wobbliness
  • • drooling
  • • vomiting
  • • urinary accidents

What to do

Keep the cat safe from stairs and bathtubs. Call a vet, especially if the edible had chocolate or the cat is unresponsive.
