Well, I finally took the old girl in for her hair pulling and the vet was clueless as to why...could be stress, allergy, reaction to a nasty yeast infection she has in her ears (yuck!). The vet put some stuff in her ears and about 5 minutes after getting her home my cat completely freaked out. Her left eye rolled back (the vet called it her third eye? this is common?) she was staggering around, falling down. Howling more than usual. Needless to say, I was freaking out completely so I rushed her back to the vet. They have no idea why she is doing this either! Apparently, they are calling the new problem "Feline vestibular disease" or "Idiopathic vestibular disease." I looked it up on the internet and it's a neurological problem caused by inner ear, stress, ...takes about 2-3 weeks recovery. So I put up a baby gate upstairs so in her drunken stumbling she doesn't fall down the stairs. They also took some blood work and her sugar is through the roof (270), 300 is diabetic so I have to take her back in next week. While I know she is old (20 yrs), it's sort of scary to have her fall apart on me all the sudden. The vet said that the next step with the "feline vestibular disease" would be to see a neurologist if it doesn't get better- not sure I'm ready for all this! Thought those that posted to my inquiry about my crazy cat might want to know.
