Cats often show interest in human foods. Broccoli is one vegetable that raises questions for many cat owners. This guide covers if broccoli is safe for cats, its benefits, risks, and how to serve it. We base this on reliable vet advice and recent studies as of 2025.
Is Broccoli Safe for Cats?
Broccoli is not toxic to cats. Vets confirm it appears on no lists of harmful plants or foods from groups like the ASPCA. Cats can have small amounts without harm. It fits as a treat, not a main meal. Cats need meat-based diets as obligate carnivores. Vegetables like broccoli add variety but stay secondary.
- No known poisons in broccoli for cats.
- Safe for most adult cats and kittens over 12 weeks.
- Check with your vet first if your cat has health issues.

Health Benefits of Broccoli for Cats
Broccoli offers some nutrients that support cat health. It has fiber, vitamins, and minerals. These help in small ways when added to a balanced diet.
- Fiber: Aids digestion. Helps with constipation or loose stools by adding bulk.
- Antioxidants: Fights cell damage. May lower risks of some diseases over time.
- Vitamins: Includes vitamin C and K. Supports immune function and blood clotting.
- Low calories: Good for weight control. Replaces higher-fat treats.
Studies from places like Johns Hopkins show broccoli’s role in health, though most focus on humans. Cats gain similar perks in moderation. Pair it with meat for best results.
Potential Risks of Feeding Broccoli to Cats
While safe, broccoli can cause issues if given wrong or too much. Watch for signs of upset.
- Gas and bloating: High fiber may lead to discomfort. Start small to test.
- Choking: Tough stems or large pieces pose risks. Always chop fine.
- Digestive upset: Vomiting or diarrhea if new to the diet. Stop if this happens.
- Overfeeding: Too much crowds out needed protein from cat food.
Raw broccoli is harder to digest. Cooked versions reduce risks. Avoid seasoned broccoli with salt, butter, or onions, as these harm cats. If your cat shows allergy signs like itching, see a vet.

How to Feed Broccoli to Your Cat
Prepare broccoli simply to keep it safe. Follow these steps.
- Wash well to remove dirt or pesticides.
- Steam or boil until soft. Avoid frying or adding oils.
- Chop into tiny pieces, smaller than a pea.
- Serve plain, cooled to room temperature.
- Mix with regular food or offer as a treat.
Stems and leaves are fine if softened and cut small. Kittens can try after weaning, but in very small bits. Use broccoli to hide pills if needed—see our guide on how to give a cat a pill.
How Much Broccoli Can Cats Have?
Keep portions tiny. Treats should make up less than 10% of daily calories. For an average 10-pound cat, that means about one teaspoon chopped, once or twice a week.
- Start with a fingernail-sized piece.
- Watch for 24 hours after first try.
- Adjust based on your cat’s size and reaction.
Too much fiber can dehydrate cats. Ensure fresh water is always available. For age-specific advice, use our Pet Age Calculator.
