About the Cornish Rex
Many owners will keep food on hand at all times and allow their rex to free feed because the breed is active enough to burn calories nearly as quickly as they take them in, and weight gain is uncommon.
The breed does not thrive in colder climates. As a result, when they sit down, they will always strive to find the hottest spot in the room to sit. On the other hand, because their coats lack the layers that other cats have, the Cornish rex has little protection from direct sunlight, which can lead to sunburn if exposed for an extended period of time. These kittens are unquestionably indoor cats.
Cornish rex is a breed that is incredibly gregarious, gets along well with other animals, and acts as a velcro cat, sticking to your side as you go about the house. She can, however, play independently, which means she can perform well on her own for long periods of time if she is taught to do so at a young age.

Care and grooming
