Our 13 year old cat Bubba has been having some "spells" in which he loses his balance and/or falls to one side, and can't seem to get up for a few seconds. We have observed this three times now, and the episodes last from 30 seconds to 1-2 minutes. Yesterday he also had some side to side eye/head movements during the spell. He seems a little confused and slightly zoned afterwards, but not knocked out tired or anything. He has no loss of bowel or bladder control. We took him to the vet after the first one, and he passed his blood tests and neurologicial exam. I have researched on the net, and found info about feline vestibular disease. Does any one have any experience with this disease? Do the symptoms come and go like this, or once they hit are they constant? It is really frightening to watch this! Thanks for any light you can shed on this. . .
