As a cat owner, you likely want to provide your cat with a nutritious and balanced diet. You may have wondered if human foods like Brussels sprouts can be part of that diet.

Can Cats Eat Brussel Sprouts

Brussels sprouts are not toxic to cats and can be fed in moderation. They provide vitamins, minerals, antioxidants, and other beneficial nutrients.

However, there are some important considerations when feeding Brussels sprouts to cats.

An Overview of Brussels Sprouts for Cats

An Overview of Brussels Sprouts for Cats

Brussels sprouts are a type of cruciferous vegetable in the same family as broccoli, cauliflower, kale, and cabbage. They resemble tiny cabbages and grow on a stalk in bunches.

Brussels sprouts provide many health benefits for humans, and they can also be good for cats. Brussels sprouts contain vitamins C and K, fiber, folate, iron, potassium, antioxidants, and more.

However, cats are obligate carnivores, meaning they thrive on meat-based diets. Vegetables like Brussels sprouts should only be an occasional treat or supplement, not a dietary staple.

When preparing Brussels sprouts for your cat, proper cooking and portion size are key. Read on for more details on safely feeding cats Brussels sprouts.

Do Cats Like Brussels Sprouts

Since cats are carnivores, they are not naturally attracted to vegetables. Some individual cats may show interest in Brussels sprouts, especially if they see their owner eating them. But many cats will turn up their nose at this unfamiliar food.

If you want to find out if your cat likes Brussels sprouts, start by offering a tiny portion of well-cooked, bite-sized pieces. See if your cat sniffs it, licks it, or eats it. Never force a cat to eat something new if it seems disinterested or distressed.

Cats appreciate routine and familiar foods. Introduce new foods slowly and in very small amounts. Make Brussels sprouts a rare treat rather than a regular part of your cat’s diet.

Are Brussels Sprouts Safe for Cats to Eat?

Brussels sprouts are generally safe for cats, as long as a few precautions are taken:

  • Serve Brussels sprouts cooked, never raw. Raw Brussels sprouts are hard for cats to digest.
  • Remove any seasonings, oils, salt, pepper, onions, or garlic, as these can be toxic to cats.
  • Chop Brussels sprouts into bite-sized pieces to reduce choking risk.
  • Introduce gradually and feed in moderation to avoid digestive upset.
  • Monitor your cat for signs of allergic reaction or intolerance.

Brussels sprouts grown in warm, humid conditions can harbor bacteria like Salmonella and E. coli. Thorough cooking destroys any potentially harmful bacteria.

Health Benefits of Brussels Sprouts for Cats

When fed properly and in moderation, Brussels sprouts can provide health benefits for cats:

  • Vitamin C – Important for immune health and wound healing. Cats produce their own vitamin C but can benefit from more.
  • Vitamin K – Essential for proper blood clotting and bone metabolism. Supports wound healing.
  • Fiber – Promotes healthy digestion and may help with weight management.
  • Antioxidants – Help protect cells from damage caused by free radicals. Reduce inflammation.
  • Potassium – Helps nerves and muscles function properly. Supports hydration.
  • Iron – Helps transport oxygen in the blood as part of hemoglobin.

While cats don’t require vegetables, the nutrients in Brussels sprouts can complement their meat-based diet. Always consult your vet before significantly altering your cat’s diet.

Are There Any Risks With Feeding Brussels Sprouts to Cats?

There are some potential risks to be aware of when feeding cats Brussels sprouts:

  • Digestive upset – Too much fiber and unfamiliar foods may cause vomiting, diarrhea, gas, or constipation. Introduce slowly.
  • Allergies – Cats can develop food allergies or sensitivities to new ingredients. Watch for itching, swelling, etc.
  • Choking hazard – Raw or improperly cut Brussels sprouts can get lodged in the throat. Always cook and cut into pieces.
  • Nutritional imbalance – Vegetables should not replace meat in an obligate carnivore’s diet long term.

Toxicity is not a major concern with Brussels sprouts themselves. But any added seasonings or cooking methods involving onions, garlic, oils, etc. can be very harmful to cats.

Can Cats Eat Raw Brussels Sprouts?

It’s best to avoid feeding cats raw Brussels sprouts. The tough, dense texture makes raw Brussels sprouts a choking risk. Plus, raw sprouts may contain dangerous bacteria like Salmonella.

Thorough cooking is necessary to kill any bacteria and make the Brussels sprouts easier to chew and digest. Lightly steam or boil Brussels sprouts until soft before feeding to your cat.

How to Prepare Brussels Sprouts for Your Cat

When preparing Brussels sprouts for your cat, follow these steps:

  • Wash fresh Brussels sprouts well. Discard any discolored or damaged ones.
  • Trim the end and remove any wilted outer leaves. Cut larger sprouts in half.
  • Place sprout pieces in a steamer basket or saucepan with about 1 inch of water.
  • Steam over boiling water for 5-7 minutes until tender when pierced with a fork.
  • Allow to cool slightly. Chop steamed sprouts into bite-sized bits.
  • Start by offering your cat just a few pieces at a time. Gradually increase portion if well tolerated.
  • Avoid adding any butter, oils, salt, pepper, or other seasonings.

Light steaming is ideal, as it softens the texture without destroying nutrients like vitamins C and K through overcooking. Never season with anything potentially toxic to cats like onions or garlic.

How Much Brussels Sprouts Can Cats Eat?

Brussels sprouts should only be an occasional treat for cats, not a dietary staple. Start by offering just a few bite-sized pieces once or twice a week.

Monitor your cat’s stool and appetite closely when first introduced. If any digestive upset occurs, discontinue feeding.

If Brussels sprouts are well tolerated, veterinarians recommend limiting them to about 1-2 teaspoons per 10 pounds of body weight, once or twice a week. Any more may lead to gastrointestinal issues.

The small serving size ensures cats get the benefits without overloading on fiber or disrupting their primarily carnivorous diet. Consistency is key—don’t swap out their regular food too often.

Other Vegetables Cats Can Eat

Other Vegetables Cats Can Eat

In addition to Brussels sprouts, cats can enjoy these other healthy veggies in moderation:

  • Pumpkin – Fiber aids digestion. Vitamin A benefits the skin and coat.
  • Carrots – Beta carotene is good for the eyes and the immune system.
  • Peas – Packed with vitamins C, K, A, B1, B2, B3, and B6.
  • Green beans – Low calorie. Contains iron, magnesium, and potassium.
  • Broccoli – High in vitamins C, K, A, B6, and folate.

Focus on vegetables high in nutrients cats need. Always cook thoroughly, introduce slowly, and stick to minimal portions to avoid problems. Consult your vet if changing your cat’s diet significantly.

Are There Any Alternatives for Cats That Don’t Tolerate Brussels Sprouts?

If your cat doesn’t care for Brussels sprouts or experiences digestive upset from them, some alternatives to try include:

  • Lean meats like chicken, turkey, or fish provide protein and nutrients without extra fiber.
  • Cat grass satisfies cats’ natural desire to munch on greens.
  • Carrots are more easily digested than cruciferous veggies.
  • Pumpkin, as long as not heavily spiced, can soothe digestion.
  • Probiotics support healthy gut flora. Great for sensitive stomachs.
  • Catnip offers a different green treat that most cats go crazy for!

As obligate carnivores, cats don’t require veggies in their diet, so don’t worry if yours turns up their nose. Focus on nutritionally balanced cat food, and offer people foods sparingly.

Can Kittens Eat Brussels Sprouts?

It’s best to wait until kittens are fully weaned, around 12 weeks old, before introducing new foods like Brussels sprouts. Their digestive systems are quite sensitive.

When your kitten reaches about 6 months old, you can begin offering a small taste of cooked Brussels sprouts every so often. But monitor very closely for any digestive upset.

Kittens have higher calorie needs for growth and should not fill up on veggies. Keep sprouts to just a bite or two for kittens under 1 year old. Their diet should be primarily kitten formula and food.


Brussels sprouts are not toxic or harmful to cats when fed properly and in moderation. The vitamins, minerals, and antioxidants can provide health benefits as an occasional treat.

However, cats do not require vegetables in their diet. Introduce Brussels sprouts slowly and carefully watch for adverse reactions. Always cook thoroughly, chop into bite-size pieces, and limit portions to avoid digestive upset.

While cats may show interest in nibbling our healthy veggies, their main nutrition should come from quality cat food and proteins. With some common sense precautions, though, small portions of Brussels sprouts can provide a beneficial dietary boost.

As a proud cat owner, I can't imagine life without my kittens. Ever since I adopted my first cat, Fluffy, as a little girl, I've been hooked on everything cats. Now as an adult, I'm lucky enough to share my home with not one, but three lovable kitties - Fluffy, Mittens, and Tigger. They bring me amusement and comfort with their silly behavior and personalities.

Fluffy, my first cat, is now 15 years old but still acts like a playful kitten. She loves nothing more than a good game of chase the mouse toy or bat the pom poms around the house. Despite her age, she pounces around with astonishing agility. Fluffy also enjoys curling up on my lap for naptime and kneading her paws into my legs as I gently stroke her soft fur.

Mittens and Tigger are brother and sister from the same litter I adopted 5 years ago. They love to play fight, chasing each other and wrestling over toys. Mittens is the more timid one - she likes to hide under the bed when strangers come over. But once she gets comfortable, she'll come out for ear scratches. Tigger, on the other hand, is bold and adventurous. He'll explore any space and make friends with anyone. But at the end of the day, these two are the best of friends and love snuggling up for naps together.

As any cat owner knows, living with cats is a constant adventure. As cat admirer I love sharing my experiences and cat tips with others. Stay tuned for more tales, photos and insights into life with the most marvelous mammals - cats!
