I had the scabs problems with Minu on her back, She used to scratch and bite her back all the time; I would check for fleas, put her on flea med, to no avail. Minu is a Persian, also, with the scratching and the scabs she was loosing hair, her fur was thinner and thinner. I don't know why or how, but one morning I was having my breakfast and she jumped at the table for some TLC. I suddenly saw the furminator and began to brush her. Of course the furminator teared off the scabs and she bled a bit, so I applied some oxygenated water, peroxide I believe is called H2O2. Doesn't sting, doesn't bother, so is good for her and I (no need for chasing a scared cat in pain). Suddenly, this became our daily routine. She has no scabs at all now, in her case, I think her skin needed to breath. I'm not saying this is a solution for everybody, I'm just saying it worked for Minu and I.
And here she is, doing what she loves to do best... sleep of course!
