We don't know what the cause was when she had the first one, but since she had a few within a month the Vet recommended to put her on her medication. Since then, this was a year ago to be exact, she's had maybe three episodes, two which happened b/c we didn't give her the pill (we missed two dosages) and the last one was this weekend but we didn't miss the pills this time. I don't know what the cause is......We are hanging in there, thank so much for your words
