Thanks, XXXXX XXXXX In combing and brushing Cogent, I have not observed any live mites. What I have observed, however, is small, scab-like "things" attached to the roots of the hairs that I have brushed/combed out....no movement with these observations. Maxine, her sister, has no such issues. Maxine is on a new diet of Hill's MD wet food. Cogent is still on dry food. My first indication of change with Cogent was small, bump-like "things" on her skin. After combing/brushing thoroughly, no bumps returned. No lesions, no open sores. No scratching of the ears or even of the skin. Unlike Maxine, at this time, no hair loss, and her coat is very thick. Appetite is normal, bowels, etc. normal, affect is normal, but she is obviously itching.
In review, about 10 days ago, I used a new cleaner to the wood floor. I don't know if this is significant, but I am considering all possibilities.
Additionally, no discharge from ears....I always had Collies in the past, and as outside pets, have dealt with ear mites, but as house cats, I am still trying to figure this out.
Thanks so much for your help!
