They’re also considered good choices for people with allergies.

There can be a great deal of variation in how individuals react to cats of different breeds and even to individual cats of the same breed. Some people can be around one type of relatively hairless cat without having problems, while another causes them to reach for the Kleenex.

People can also be fine around one Sphynx cat and start sneezing when another walks into the room. There are several proteins that can trigger allergy symptoms, and cats all have unique protein mixes, which can cause varying reactions in humans.
