Questions about Butternut Squash

Is butternut squash toxic to cats?

No, butternut squash (Cucurbita moschata) is non-toxic to cats. It is classified as generally safe, meaning it poses no known toxic risk.

What happens if a cat eats butternut squash?

Most cats will have no reaction at all. If a cat eats a large amount of raw or fibrous butternut squash, mild vomiting or diarrhea is possible due to the fibrous plant material, not any toxic compound.

How much butternut squash is too much for a cat?

There is no established toxic dose because butternut squash is non-toxic, but large quantities of raw, fibrous material can cause mild digestive upset. Small, cooked amounts are far less likely to cause any GI discomfort than large amounts of raw squash.

Should I be worried if my cat ate some butternut squash?

A small amount is not cause for concern — butternut squash is non-toxic to cats. If your cat consumed a large quantity and is showing signs of distress such as repeated vomiting or diarrhea, contact your veterinarian for guidance.
