How do you know that cats are healthy?

It can be judged from the following aspects: first, from the spiritual point of view. Healthy cats are in a good state of mind and will be particularly energetic, while cats will look listless when they are sick. Secondly, observe from the aspect of appetite. A healthy cat has a good appetite, but after illness, the cat's appetite drops and it won't even eat its favorite food. Moreover, cats don't like activities after illness, and they like to hide and lie down.
