While I'm not a vet, biolgically, anything with a brain is capable of suffering a seizure. The episode described would be considered partial-complex, and 15 min. is a long time. Additionally, a 4 hour postictal state would also be highly unusual. It certainly is an interesting question. Brain tumors have been associated with extended periods of abberant behavior in humans. I'd like to hear a DVM comment on ferret CNS disease. Robert Butler, Ph.D. OHSU Portland, OR [Moderator's note: Alas, California Fish & Game isn't capable of suffering a seizure.
