Accepted botanical classification for Cucurbita maxima.
Buttercup squash (Cucurbita maxima) is considered non-toxic to cats. It is classified as generally safe, meaning it is not expected to cause poisoning or serious harm.
No symptoms are expected from small amounts. If your cat eats a large quantity of raw, fibrous squash material, it may experience mild vomiting or diarrhea due to the high fiber content, not any toxic compound.
Monitor your cat for signs of GI upset such as vomiting or diarrhea. If symptoms appear or your cat seems distressed after eating a large amount, contact your veterinarian.
Cooked squash is softer and lower in raw fiber, so it is less likely to cause the mild digestive upset that large portions of raw, fibrous squash material could trigger. Either way, buttercup squash is non-toxic to cats — the concern with large ingestions is GI irritation, not poisoning.
Yes, buttercup squash (Cucurbita maxima) is considered non-toxic to dogs. It is not expected to cause harm in typical amounts, though non-toxic does not mean dogs should eat it freely or in large quantities.
Large amounts of raw, fibrous squash material may cause mild vomiting or diarrhea due to the bulk and fiber content. The plant itself is not toxic, so symptoms should be minor and self-limiting.
A small amount is unlikely to require a vet call. If your dog ate a large quantity and is showing signs of distress such as repeated vomiting, significant diarrhea, or lethargy, contact your veterinarian.
Raw buttercup squash is more likely to cause digestive discomfort because the dense, fibrous flesh is harder to process; cooked squash is softer and easier on the gut. Either way, the plant is non-toxic — any GI upset from large ingestions is mechanical, not due to a toxic compound.
