Thank you for the info on wobblers, she really doesn't show any signs beyond the lack of balance or control of her hind legs.
UPDATE...
Tig is still falling down, 3 months after her vet visit, which, after a full blood workup was done, she is healthy in all other respects of her life. She has lost a little weight, and we have added a few carpet runners in the hall ways.
