if he has fleas you will need to get a flea product from your Vet(not from stores) and treat them properly with more than shampoo.
also do not give flax seed oil to cats.......what he needs is omega 3 fish oils...they come in a capsule, pierce the capsule and squirt in his mouth or if he will eat it ok add it too his food....krill oil or salmon oil omega 3's are the best....get ones without additives.
good luck
Thank you so much. I realized when Iooked at the photos, that my cat's skin is not inflamed. I have been giving him flax seed oil and a flea shampoo. The bald spot is no longer getting bigger and some hair is starting to grow. I will let you know if he keeps getting better.
Lois I just found another site that may give you more info this one also has photos, keep us updated ok..good luck

Thanks so much for the tip Opus88. Mange just might be the problem. My friend looked at the bald spot last night and asked if I had changed his diet, and I recently did. I will try going back to his previous food as well. With appreciation.
gee I'm not sure???? could be demodectic mange???? I will send you some info on that....you really really need to take this poor kitty to a Vet and get it some help, this sounds very painful...
let us know when you find out what it is for sure okay....good luck.
