Anyone have a cat with seizures?

[starryfish]

My cat was on the streets the first year of his life. I have had him for 6 years and he has had seizures 1-3x a month but we never medicated him bc they were super short and not often. Last week he started having them much more often (6+ a day) so I took him to the vet. His bloodwork is all normal so vet thinks it's a trauma that occurred when he was a baby. She's not sure what to give him bc she says its so rare and is waiting on a specialist to get back to her. In the meantime he has been on Valium but he is constantly meowing (attention meow not pain). Just looking for advice! Thanks!
