I had some experience with feline epilepsy many years ago. My Cassandra suddenly had one, and off to the vet we went. There was no known cause for it, so he put her on phenobarbitol. It was so long ago that I cannot remember how long she stayed on it, but I do know we eventually took her off it, and she never had another seizure. She lived to be almost 18.

Althea had one several weeks ago - not a lot of thrashing, but she wobbled when she tried to walk, and then fell over onto her side. To say I was frightened doesn't even begin to describe what I felt! By the time I had the hospital on the phone (she had just been seen by her doctor about an hour previously), she was fine. When I spoke with him and we discussed what had happened (she'd had some diarrhea, and I'd had to wash her tail end), the doctor said that it was, indeed, a "mild" seizure most likey brought on by the stress of my washing her. She had fought me really, really hard. Since Pip has seized more than once, stress is probably not the cause, but it is something to keep in mind.

Best of luck to you and Pip!
