Although they're not essential to a cat's diet, veggies like broccoli, cucumber, green peas, and carrots are high in water content, vitamins and minerals, and sometimes high in fibre — all good for cats. Though many cats have an aversion to the taste of vegetables, Dr. Kirk said.
"Boiled peas are a great source of protein and a very nutritious supplement to a healthy diet," Dr. Ochoa said, noting that potatoes can also be eaten cooked or boiled. However, you should only give your cat about one tablespoon of potatoes per feeding since cats do not need a high carbohydrate intake.
