Scabies, also known as mange, isn't often found in cats, but it is certainly possible. The mites that cause mange are found on cats and people as well as on dogs. If you have rescued a dog or a cat or you have experienced scabies on your skin, it can be a miserable experience. It is also highly contagious.

How is Scabies Different in Dogs, Cats and Humans?
Because mites like particular temperatures, most mites are species specific. This means mites which find your dog's skin a comfortable home will not find your cat's skin a comfortable home. These mites will also not like to live on your skin. Body temperatures vary from species to species, so mites tend to stick with one species and not to cross from one to another. Although, it is possible mites may migrate somehow from your dog's skin to your own or vice versa. However, they will not thrive and reproduce on another species’ skin as they do on the skin of the species which they are most comfortable. The exception, of course, are the sarcoptic mites which cause scabies and mange in cats, dogs, humans, as well as other mammals.
With these mites and sarcoptic mange, the signs and symptoms and manifestation are going to be very similar from species to species.
A family moves to a new home. Down the street is a construction site filled with dumpsters where workers often placed their leftover lunches along with building materials. This construction site is known for having stray cats as well as a few stray dogs. These cats, being very familiar with their environment and very comfortable with people as well as dogs living around them, come to the family's new house and make friends with the people and the family dog. Some of these cats have mange so bad the scabs and black spots around their eyes and ears can be seen as they walk up the driveway. The family dog, however, does not care that the cats have mange. He just wants to play. It takes a couple of weeks before this family dog starts to develop itchy spots and sores on his skin, leaving the owners to suspect he also has mange. Because scabies and mange, if caught early enough, can be treated by your veterinarian, this family decided to do sulfur dips for their dog and shampoos to help heal their skin and rid the skin of mange. After a couple of weeks, their dog was fine and the scabies did not turn into an infection. However, this community had a problem with stray dogs and stray cats that were passing scabies from one to another. This community, with the help of volunteer veterinarians, came in and not only dipped all the animals and gave them all antibiotics, but also spayed and neutered all the stray animals they could capture to keep the population from growing. It is a case like this where a family dog is affected by the stray, homeless animals living around them which brings a community together to care for the animals who are surviving but also possibly passing disease and illness to the domesticated pets in their community.
