Animals can show signs of toxicity after ingesting 1.5 mg per kilogram of body weight and Hunter may have ingested over 7 mg per kg. I would be concerned about the potential for serotonin syndrome secondary to this medication. It could cause agitation, high heart rate or blood pressure, muscle tremors or seizures. I would recommend seeing an emergency veterinarian to discuss treatment. Attempting to induce vomiting might be recommended if he ate the pill recently, but it can be difficult to get cats to vomit. Otherwise the recommended treatment would probably be IV fluids and monitoring in the hospital.
