You might want to look at some of our other products, too. DERMA-IONX which is an oral homeopathic product stimulates the enzyme systems in the body which reduces itching and inflammation, promotes healing of the skin and helps with assimilation of nutritional components in diet and supplements. The supplements I use alongwith it include PROBIOTICS and OMEGA 3,6,9. Together with DERMA-IONX it produces a synergistic effect. I would also suggest that you give your cat only filtered water for drinking and bathing if your water contains chlorine or fluoride. As for diet, if your cat is not allergic to these protein sources you might try a fish or turkey based grain free food.
These foods are considered to be cooling according to Chinese food therapy. You would want to avoid chicken or lamb which are warming for the skin if it is already too warm. Beef is neutral. Avoid treats that have artificial colorings.
You might also ask your veterinarian to check a stool sample if it has been a while since it was last checked. Please feel free to contact us again if you have any other questions or to let us know how you are doing. We can suggest more things to do depending upon the response you get from the above.
