Cats can eat peanuts. Peanuts are rich in fat, starch, trace elements, and vitamins, and do not contain any harmful ingredients. They can provide cats with additional nutrition. However, because peanuts are high in fat, they should not be given in excess, as this can easily lead to obesity. It is recommended to limit consumption to 4-5 peanuts per day.

In addition, spicy foods such as onions, scallions, garlic, ginger, and pepper can damage a cat's red blood cells, causing hemolysis and irritating its gastrointestinal tract. Chocolate and tea contain theobromine, which can cause poisoning in cats.
