Topiramate is a newer anti-epileptic drug that has shown efficacy in the treatment of seizures in people. However, there is limited data on this medication in veterinary medicine. In order to use a medication appropriately, an accurate dosage and dosing frequency must be determined. This study will be performed in two phases. Phase one will establish the dosing parameters for extended release topiramate in cats. Phase two will establish plasma levels following multiple doses as well as identify any side effects related to the medication.
