How long does 1mg of xanax stay in a cat system?

Cats are very sensitive to Xanax and even small doses can cause toxicity. The elimination half-life of Xanax in cats is approximately 6 hours, but it can take up to 24 hours for the drug to be completely eliminated from the body. Because cats are so sensitive to this medication, it is important to consult a veterinarian before administering any medication to a cat.
