I treated my stray female cat Trixie who had lost all of her fur from her waist to the tip of her tail (from mange) with organic apple cider vinegar. I diluted it to around 1 part ACV to 10 parts water then sprayed her body every other day within 2 days she had stopped itching and within 2 weeks new hair had started to grow back. Six weeks later she had the thickest shiny hair you have ever seen. My neighbours were shocked. 2 years later and still everything is OK. Better than anti-biotic and steroids and a huge vet bill.
I put a half teaspoonful of organic apple cider vinegar in my cat's water fountain every week to prevent cystitis which can be painful and costly.
