" I have a long haired black cat, and her hair is thinning or she is completely losing it in patches, especially in the back, around her tail, back legs, and lower back. Any ideas what may be causing this? "
This exact thing happened to one of my cats and it turned out to be food allergies. As soon as I switched her to high quality holistic grain-free natural foods ( Wellness Core and wellness grain-free canned , Taste of the Wild, Innova Evo canned, Nature's Instinct raw medallions, California Natural Salmon and Sweet potato canned ) and it stopped almost instantly and now her coat is thicker and more luxurious, shiny and soft than ever. Also make sure she gets supplements of Brewers Yeast and Garlic tablets, salmon or flax oil in the diet as well.
