hi, my 2 3/4 year old cat has started acting funny out of the blue...first he started wabbling is rear end when he sneezed or shook his head, it got worse the next day so i took him to the doctor...the doc. prescribed a 10 day cycle of antibiotics due to a possible inner ear infection because he could not find anything physically wrong with shadow...the blood work also showed nothing irregular,,,,so that night shadow got worse and his eyes started tracking the room like he was extremely dizzy or something, then he started shaking his head like his ears were bugging him....over the next few days he got a little better but he is still off balance, mainly when he shakes his head or tries to rub on something or right after he jumps up on something, he will just fall over....i can see that he is not in any pain, but i would like to know what is going on...ive been reading about cat strokes, and inner ear infections.....these two options suit his symptoms best. he is going on seven days of treatment but is still off balance ....he still eats and drinks and pees and poops, what is your opinion....the blood work showed no increase in white blood cell count so an inner ear infection is unlikely...help please
