Hi there and thanks for posting on Petco Pet Education Center, formerly Petcoach

4oz of coffee contains approximately 68mg of caffeine which may be concern. Symptoms of caffeine toxicity can start to occur at 15mg of caffeine per kg of body weight. For a 10lb cat, this places Cleo right at the 15mg per kg dosage.

At this point, I would monitor her at home very closely. If Cleo begins showing symptoms such as vomiting, diarrhea, hyperactivity, restlessness, increased urination, tremors, seizures, panting, or heavy breathing, please take Cleo to an emergency veterinary clinic right away.

I hope this helps and I wish you and Cleo the best!
