My kitten is 6 months he has been having fits he has had like 6 that I'm aware of we have had all bloods done I'm worried sick how is your kitten.....I think the not being able to see, acting strange for a few hours after a fit is normal. My cat does that. He acts very oddly like he has a bad taste in his mouth and can't see properly, and meows a lot. It is something to do with the fit.
Let us know what the vet says
