Can you eat it?

For peopleNot well documented

None of the sources we checked (NC State Extension (no page for this plant), USDA PLANTS) say whether it's edible or poisonous for people.

For petsNon-toxic to dogs, cats and horses

ASPCA's entry “Yellow-Flowered Gourd” (Cucurbita species), which covers the whole genus, lists it as non-toxic to dogs, cats and horses. Eating lots of any plant can still upset a pet's stomach. ASPCA
