Cats are too thin when they are picky about food. Feeding cats with canned cats or boiling chicken breast in white water can increase the nutrition in the body. Over time, the cat's body will be strong. Cats may be picky eaters because they don't like cat food and canned cats, or they should change to a cat food with higher nutritional value. The behavior of picky eaters needs to be corrected gradually, otherwise it will affect the health of cats.
