There are two things you need to know about these cats: they are very active and energetic and very people-oriented.
Despite their skinny, delicate look, Cornish Rexes are no weaklings, they are physically strong and they love using their muscles. Your Cornie will jump and run and play and run and jump until he is exhausted, then he’ll be out cold for a while, and then back to his games with renewed vigor. And he will never grow out of it. Cornish Rexes always remain kittens in their heart, they will entertain you with their kitten-like antics for the rest of their life. Cornish Rexes are known to play fetch, open doors and cabinets, do back flips off the walls, race around the house and ambush their owners and other pets. Have you ever been around a British Shorthair who is the embodiment of dignity? Cornies are the opposite, they are the embodiment of fun.
With all their energy and agility, Cornish Rexes are also very affectionate. Their very short fur makes them appreciate a warm lap, and, as I’ve already mentioned, they are very friendly and people-oriented by nature. They love to be held and love to cuddle next to their owner, especially under the blanket. They enjoy interacting with humans, they will follow you everywhere and try to participate in everything you do. You don’t have to do “cat” activities to get their attention: toys and strings are of course a lot of fun, but watching you wash the dishes is no less fascinating for them. If you don’t think you have enough time for regular fellowship with your Cornie, you shouldn’t be getting one. When it comes to fellowship, Cornish Rexes can be described as “needy.” Yes, they need you to be there for them, love them, hug them, and talk to them. They also like the company of other cats and, if properly introduced, will get along well with dogs.
