Can Cats Eat Butternut Squash?

Yes — plain cooked butternut squash is not toxic to cats, but it should only be an occasional small treat. Cats are obligate carnivores, so squash is not a necessary part of their diet and too much can cause stomach upset.

Butternut squash is generally safe for cats in small amounts

Butternut squash is listed by the ASPCA as non-toxic to cats. The main concerns are digestive upset, choking, or blockage if your cat eats raw squash, tough skin, seeds, or heavily seasoned squash dishes.

How to Safely Feed Butternut Squash to Your Cat

If your cat likes butternut squash, offer only a very small amount of plain cooked squash as an occasional treat. It should never replace a complete and balanced cat food.

  • Serve only cooked squash — steamed, baked, or boiled until soft
  • Remove the skin and seeds before offering any to your cat
  • Keep portions tiny, such as 1 to 2 small teaspoons mashed or finely chopped
  • Serve it plain with no butter, salt, sugar, onion, garlic, sauces, or spices
  • Introduce slowly and stop if your cat develops vomiting, diarrhea, or refuses food

Common Questions

Is butternut squash toxic to cats?
No. The ASPCA lists butternut squash as non-toxic to cats. That said, non-toxic does not always mean risk-free — raw pieces, skin, seeds, and rich seasonings can still cause problems.
Can cats eat raw butternut squash?
It is better not to feed raw butternut squash. Raw squash is hard, difficult to chew, and harder to digest, which increases the risk of choking, vomiting, or gastrointestinal upset.
Can cats eat butternut squash soup or roasted squash with seasoning?
No. Many squash recipes contain onion, garlic, cream, butter, salt, or spices that are not appropriate for cats. Only plain cooked butternut squash is a reasonable option.
How is this different for cats vs dogs?
Butternut squash is generally considered non-toxic to both cats and dogs, but cats should get much smaller amounts. Because cats are obligate carnivores, vegetables are less appropriate nutritionally for them than for many dogs, and rich or excessive plant-based treats are more likely to cause digestive upset.
What symptoms should I watch for if my cat ate too much butternut squash?
Watch for vomiting, diarrhea, decreased appetite, lethargy, gagging, trouble swallowing, or signs of abdominal discomfort. Call your vet promptly if symptoms are persistent, severe, or if your cat ate raw chunks, skin, seeds, or a seasoned squash dish.
