We just got back from the neurologist. He says that he doesn't think that she is having seizures after all (I swear every vet I talk to tells me somehting different), but he does think that she has something neurologically 'off' about her because of the way she is walking (she is a little unstable and lifts her front legs very high, and also frequently walks looking up, which is apparently abnormal). He has advised us to keep a log for the next month and check back in.
I consider it great news that he didn't think it was as bad as the other vet did
