Canine distemper (sometimes termed footpad disease) is a viral disease that affects a wide variety of mammal[2] families, including domestic and wild species of dogs, coyotes, foxes, pandas, wolves, ferrets, skunks, raccoons, and large cats, as well as pinnipeds, some primates, and a variety of other species. Animals in the family Felidae, including many species of large cat as well as domestic cats, were long believed to be resistant to canine distemper, until some researchers reported the prevalence of canine distemper virus (CDV) infection in large felids.[3] Both large Felidae and domestic cats are now known to be capable of infection, usually through close housing with dogs[3][4] or possibly blood transfusion from infected cats,[3] but such infections appear to be self-limiting and largely without symptoms.[4]
