Negs, my Cleo had horrible skin problems. Keep up the olive oil flax seed oil ect..That will help. Also after doing a bunch of research and looking for more natural solutions (how I found out about the flax seed and fatty acids ect..) one site I was on which was excellent ..sorry I thought I had it book marked but I guess not. Suggested 2 things that I hadn't thought of or tried. 1) some cats are allergic to ..of all things CHICKEN
So I went through all the canned food and dried foods in my pet smart and bought only ones that didn;t have some sort of chicken in it. I literally pulled a can out of everything and sat on the floor and read the ingredients.
2) what kind of dish are you using to feed Tyson? If its porcelin get rid of it. If it is ceramic, get rid of it. If it has any kind of paint on it get rid of it. No plastic either. Glass or metal only. Some of the chemicals in the food and water bowls can cause allergies, rashes and pimples. I did those 2 things and Cleo is much better.
