Can you give your cat xanax?

Yes, you can give your cat or dog Xanax. You should call your vet to get the recommended dosage and start with the minimal. Animals digest the drug differently than humans do so please don't think you can figure out what is best. Consult with a veterinarian first! My 85lb dog was recommended to take a 1-4mg dosage during a thunderstorm. I gave him 1mg and he passed out in the middle of the floor for hours!
