Question

hair loss area
We have a cat whose had a 1 inch by 1 1/2 inch strip on her back/haunch for over a year. It would grow a little hair back then lose it again. Then in Oct. our other two cats each got a small spot of ringworm on an ear. We began treating with Terbinafine cream and they're practically healed. In the meantime the bare spot on the first cat has begun to spread. Has black specks on the bare skin. Vet originally said that the big bare spot didn't look like ringworm. Hair didn't lift off easily, if at all, nor were there chunks of skin that would come off with hair when lifted off as it did with the other two cats. He has tried two different times a steroid shot (with steroid pill every other day). Both times the big bare area would initially look better (more the color of normal skin). Then after about 6 days it would start to redden again and the size of the area continued to grow.  The area is about 4 by 6" now. About a week ago we also noticed a spot up on her back/neck where you'd put flea killer liquid. Vet diagnosed that as ringworm--acted very typical like the other two cats' ear spots.  We tried early on using the Terbinafine on the one cat's large bare area but it just got redder and didn't help. REcently in desperation, we've been putting an antibiotic ointment on the large area.  It may be helping some. Should we ask the vet for an antibiotic, even though he doesn't think it's bacterial, just to rule that out? He has thought it was nerves and perhaps persistent licking making the hair brittle and breaking off.  He has her currently on Amitriptylin once a day. The ringworm circle area on the back of her neck is growing at an astronomical rate, even though we try our best to place the cream beyond her hair line out into surrounding tissue to try to prevent spread. Any ideas?  Thanks so much, Sheila in OKC

Answer
This may be an area where the cat has licked or chewed the hair off the skin.  Your vet can culture the area to see if it is a ringworm problem.  You can also ask the vet to see if there is actual hair loss or if there are hair follicles in the skin where the cat has broken the hairs off.  We call this barbering.  That usually indicates itchy skin.
