The Habba Huts aren't dangerous to your snake, but the design isn't the best for Balls. Ball Pythons like very small, confined spaces that they can feel touch their sides. This isn't possible with the Habba Hut that has two opened sides. A better solution would be to use an overturned planter drip tray with a hole cut in the side or on top. Even a regular plastic bowl with a hole cut in the side would work fine.
