This is for families with pet cats. Ours used to live with our son but he moved overseas and we inherited her. For several years he spent big money on the vet to get her to stop licking the hair off her belly. She licked so much it even bled. Steroids, tranquilizers and all kinds of expensive medicines and shots did no good. One evening I was trying to think what things we had in our house that our son had in his. Different carpet, different food, different cat litter. Ah Ha! City water with all the chlorine and chemicals. We switched her to local spring water, discontinued the medicine and after 3 months she's all healed. And we cancelled her $150.00 Steroid shot.
