Cats are not cold-blooded animals, but warm-blooded animals. A cat's body temperature is usually between 38 and 39 degrees Celsius, slightly higher than that of humans. Cold-blooded animals' body temperature fluctuates with changes in ambient temperature, while warm-blooded animals can maintain a relatively stable body temperature.

Cold-blooded animals are called poikilothermic animals, such as snakes and lizards. There are many breeds of cats, with common pet cats including British Shorthairs, American Shorthairs, Siamese, and Ragdolls. Owners can choose a cat breed that suits their preferences.
