Yes, but hit it with what? A bullet or with the shotgun itself? See, it doesn’t say that she shot it, and one might conclude that, since it didn’t die immediately and survived long enough to be taken to a vet hospital where it later died, perhaps she just used the shotgun to savagely beat the animal.

I mean, if the monkey attacked her, she might not be able to get off a shot since shotguns are almost useless in close quarters. She might have had to use the shotgun to bludgeon the monkey until it stopped attacking.
