Adult cats can eat small amounts of walnut kernels, but they must be eaten under the control and inspection of their owners. Walnut kernels are rich in protein, vitamins and other nutrients. If the cat does not experience symptoms such as vomiting or diarrhea after eating a small amount, it means that the cat's body can accept it. However, the owner should still be careful not to feed it frequently and remember not to feed it too much.
