She has been to the 2 top neurologist for cats in our area and stumped both of them.
Is there any info you can give me to help her.[/quote]
Good morning Lucinda-
I'd be very curious to know what the neurologists said (can you post that info here?). Has she had an MRI/CT or spinal tap? Is her bloodwork normal?
In general, you are describing a cerebellar and vestibular problem. Basically she probably feels like the world is spinning causing her to be unstable.
The homeopathic medical model can easily explain why this started after the surgery, but that's another story. Since you have already explored your conventional options and everyone is "stumped", then you should broaden your search for help.
A trained and experienced vet homeopath will use all of her specific symptoms (not just the neuro symptoms) to help her body heal as best as it is able. Even if you don't have a local homeopath, many of us work as consultants over the phone and by e-mail. Look at http://www.theavh.org for more info and a referral.
Good luck and please keep us posted.
