Depending upon age, seizures or mini-strokes...Vet Care, Vet Care, Vet Care!!!
I totally agree.....these "attacks" sound like seizures. It sounds like your cat is having quite a few in a row. This is very dangerous and life threatening. Get your cat to the vet ASAP!
Little attacks? Do you mean seizures? Can you describe those little attacks?
Sounds like it could be neurological, in which case I recommend you take her to the vet as soon as possible. How old is she?
From what little you've told us, your cat should see a vet right away!
