The rough bumps skin indicates that something is damaging the skin. Yeast and/or bacterial infections are usually present with these cases, but there is often a primary problem. The primary problem may be any of the following: 1) Allergies - this can happen suddenly and is usually due to an environmental (i.e pollen) cause. 2) External parasites - fleas, lice and mites can all cause intense itching. It's good to check him for fleas and get treatment if needed. 3) Over-bathing, or using the wrong product for bathing - Bathing too often can cause the skin to get dry and irritated. Cats should normally be bathed no more than once a month with a shampoo that is labeled for dogs. If you bathe more than that, or use a shampoo or soap that is meant for people, then you could be damaging the normal protective barrier of the skin. 4) Autoimmune (self attacking) diseases - these are much more rare and we usually only check for these after we've ruled-out the previous causes. One thing you can do for the bumpy skin is give a bath with cool water using a medicated cat shampoo every other day until the bumps have gone away. You can get these shampoos at the pet store. I hope this helps you to identify the problem. If not, then it would be worth taking him to the vet. We can usually discover the cause quickly and provide the most effective treatment.
