Couple weeks ago I found my 2.5 yr old cat hovering in the back of a closet. When I pulled her out, I saw her eyes were fully dilated, she had trouble keeping her balance and her head was tilted. My vet was puzzled, gave her some antibiotics, anti-inflammatory's and vitamins thinking it was an inner ear infection although he couldn't really see anything when checking her ears. She was pretty lathargic. Now she seems a little more lively, is eating okay but still has this tilted head. Anybody have any ideas or have been thru this before...what can I do? Is is curable? Please help...
