Can Cats Eat Broccoli?

If your cat won’t stop sniffing your broccoli, a little plain, cooked floret is fine—in moderation.

Cats are mysterious little creatures. One day they’re refusing their expensive food, and the next they’re trying to steal a piece of broccoli off your dinner plate. Your first instinct may be to shoo them away—but can cats eat broccoli? And is broccoli safe for cats?

Yes, broccoli is safe, and cats can eat a small amount.

That said, broccoli doesn’t offer much that your cat isn’t already getting from a complete and balanced cat food. Cats are obligate carnivores, so they don’t need vegetables—even if they want them sometimes.

Before introducing any new food into your cat’s diet, always check with your veterinarian.

Can Cats Have Broccoli?

Yes, cats can have a small amount of broccoli.

Plain, cooked broccoli is the best way to go. Raw broccoli isn’t toxic, but cooked florets are usually easier for cats to chew and digest—and larger chunks can be hard to swallow.

If you’d rather give your cat the benefits of veggies without worrying about what’s safe and what’s not, consider vet-approved, nutritionally balanced treats like FurPetVo’s VeggieBlend Cat Treats, available at furpetvo.com.

Is Broccoli Good for Cats?

Broccoli can offer a few small perks for cats—but it’s still not a food they need. Most cats are better off with something more protein-forward, like tuna, than a fibrous vegetable side dish.

That said, a few possible benefits of broccoli include:

  • Fiber: Broccoli contains fiber, which may help with fullness and digestion in small amounts.
  • Water content: Broccoli has a high water content, which may be helpful for cats that don’t naturally drink much water throughout the day. While it’s not a replacement for proper hydration, foods with extra moisture can still contribute a little to overall fluid intake.
  • Antioxidants: Broccoli contains antioxidants that help protect cells from everyday stress and damage—potentially supporting healthy aging and immune function over time.
  • Low sugar and fat: Plain broccoli is naturally low in sugar and fat, making it a better snack choice than richer alternatives like bacon.

Is Broccoli Bad for Cats?

Yes, broccoli can be bad for cats if it’s prepared incorrectly—or if they eat too much of it.

Here are some potential downsides:

  • Too much fiber: While some fiber can be beneficial, too much can lead to gas, vomiting, diarrhea, or general stomach upset. Cats with a history of digestive trouble may be especially sensitive to cruciferous vegetables—even in small amounts.
  • Large pieces: Big florets and stalk chunks are tough and harder for cats to chew. These parts may become a choking hazard or pose an obstruction risk.
  • Butter and seasoning: Rich toppings and seasonings can make broccoli much harder on your cat’s stomach. Ingredients like garlic and onions are especially dangerous—they’re toxic to cats.

How Much Broccoli Can My Cat Eat?

All treats—including broccoli—should make up no more than 10% of a cat’s daily diet. The rest should come from a balanced cat food.

For most healthy adult cats, one or two bite-size pieces—about the size of your thumb (cut into smaller pieces)—once or twice a week is plenty.

How To Safely Feed Broccoli to Your Cat

While broccoli isn’t toxic, there are a few simple steps to keep it safe for your cat:

  • Steam, bake, or boil it plain—no added ingredients.
  • Let it cool completely before serving.
  • Cut it into small, bite-size pieces.
  • Skip butter, oil, cheese, salt, and seasonings entirely.
  • Offer only a piece or two—not a whole floret.

My Cat Ate Too Much Broccoli—What Do I Do?

Eating too much broccoli usually isn’t an emergency. It’s most likely that your cat will experience mild stomach upset that resolves on its own.

You may notice:

  • Vomiting
  • Diarrhea
  • Gas
  • Low appetite
  • Belly discomfort

Call your veterinarian if symptoms don’t go away within 24 hours—or if:

  • Your cat ate broccoli cooked with garlic, onions, or heavy seasoning.
  • Your cat swallowed a large piece and seems to be gagging. If your cat is struggling to breathe, go to the emergency vet immediately.
  • Your cat keeps vomiting or refuses to eat.
  • Your cat seems unusually tired or uncomfortable.

If you can’t reach your vet and you’re concerned your cat ingested something potentially toxic, call the Pet Poison Helpline (855-764-7661) for expert advice.
