Can My Cat Catch Mange From a Neighbor’s Dog?

The risk to your cat is low. Mange isn't a virus; it's caused by tiny mites, and the types that affect dogs mostly stay on dogs. Demodectic mange, which is common in dogs, isn't contagious at all. Sarcoptic mange (canine scabies) spreads easily between dogs, but cats are rarely affected by the dog form of these mites.

Cats have their own mange mite, Notoedres, which is rare in many areas and spreads mainly between cats. Cats can also pick up ear mites and a few other mites from other animals, so it's still sensible to limit close contact between your cat and a dog that's being treated for mange, and not to let them share bedding.

If your cat starts scratching a lot or develops crusts or hair loss, especially around the ears, face or neck, see your vet. Many vet-prescribed flea and parasite products for cats also help protect against mites. Never use dog flea or tick products on cats, because some, such as permethrin, are toxic to cats.
