Cold-blooded animals do not have a temperature-regulating system in their bodies, so they have no body temperature. Cats, on the other hand, have a constant temperature all year round and are warm-blooded animals. Cats can sense the warmth and coldness of the outside world and use their own systems to adjust their body temperature. There are many varieties of cats that are suitable for families to raise. They are warm-blooded animals that are loved by people for their docile personalities, soft appearance, and cute looks.
