Which animals can contract both feline and canine distemper?

Raccoons and ferrets are indeed capable of contracting both feline and canine distemper. This is due to the fact that these animals belong to families that are susceptible to the viruses responsible for these diseases. Canine distemper virus (CDV) primarily affects canines but can also infect other carnivorous mammals, including raccoons. Similarly, while feline distemper is more commonly known to affect cats, ferrets, as carnivores and close relatives, can also become infected with the feline panleukopenia virus (which is often referred to as feline distemper). This makes raccoons and ferrets unique hosts for these viruses, allowing for the cross-species transfer of disease.

On the other hand, horses, lambs, cows, and pigs do not have the same susceptibility to either canine or feline distemper viruses. These animals belong to different taxonomic classes (equine, ovine, bovine, and porcine) that are not typically affected by the viruses that cause these conditions in canines and felines. Thus, they do not exhibit the symptoms or complications associated with distemper in the same way that raccoons and ferrets do.
