Feline scabies, or mange, is caused by mites. Your cat will be itchy and irritable, shake its head a lot and lose its fur. You'll notice crusty areas around the cat's ear, neck and head. If not treated right away, the infection can spread to the whole body. Follow these steps to treat your cat at home if you choose not to take it to the vet.
Cut the cat's fur if it's long to keep it from getting matted and to see the infected areas easier.
Bathe your cat in a gentle shampoo together with a lime-sulfur dip such as Dermisil, which can be bought at a pet store or online at dermisil.com. Use an antiseptic shampoo if your cat won't object to the odor as that'll kill the mites more effectively. You may have to repeat the treatment every seven days for six to eight weeks.
Fumigate your home to rid it of mites that may be lurking where your cats sleep.
Isolate your infected cat from other pets and humans while he's being treated for feline scabies.
