I just checked him for fleas by following what you've suggested and I did not see any black specks on his skin that I could find. I don't see any discharge or redness in his ears. He was itching his ear a lot about a week ago and it was twitching but that seemed to have stopped after a day or two.
I only see the redness from his scabs that have formed under his chin, but mainly on one side of his neck.
I took him to the vet about 2 1/2 months ago and she checked for fleas at that time and said he didn't have any. Now, that I think about it, she did shave part of his chin because she saw a couple of these scab like things directly under his chin. At that time she said that it was probably cat acne.
I thought it went away, but could this be what the problem is?
I've never heard of cats having acne. This time it seems to be on the side of his neck as well and that wasn't the case before.
I was thinking of giving him a bath or possibly washing that area with warm water and mild soap, but I wasn't sure if that would be the right thing to do.
I appreciate your help and any feedback you may have. Thank you.
