1. Cats have different body postures, 2. Different states of physical health, 3. The lifespans of the two cats are also different. Wild cats have messy hair and are thin because they live outside for a long time; while domestic cats have been cared for by their owners since they were young, and their hair is thin. Smooth and shiny, with a fatter figure. And because the two live in different environments, domestic cats have much better physical shapes than wild cats.
