Benefits of Green Beans for Cats

Green beans can help cats in several ways when fed in moderation.

Supports digestion

The gentle fiber in green beans can help regulate bowel movements and support gut health.

Helps with weight control

Veterinarians sometimes recommend replacing a small portion of a cat’s food with green beans to reduce calorie intake without reducing meal volume.

Hydration boost

Green beans are full of water, which supports hydration.

Supports hairball movement

Fiber can help hair move through the digestive system more easily.

Low-calorie treat

A great alternative to calorie-heavy treats.

Antioxidant support

Green beans contain antioxidants that support the immune system and overall wellness.

While beneficial, green beans are not needed in a cat’s diet — they’re simply a safe, healthy add-on.
