My cat is around 11 yrs old, she has fallen I'll a couple of times ad bounced back but the latest one she is unable to look up without falling and keeps sliding, she stopped grooming herself and walks little fearing that she will hurt herself. She has been to 3 vets and they are unable to come with a diagnosis. She sleeps more than before and tends to sleep with her face down which she has never done before, is very skinny around 6lb and doesn't have much of an appetite. I really don't know what it is and would like to know if anyone exeprienced this before.
