Animals get stuck in the weirdest places possible. It's a genuine question to wonder how the situation came about that they end up stuck between table legs, or in a lawn chair, or in general in whatever place they manage to get themselves into, and fail miserably to extricate themselves from the situation, with the necessity of us swooping in to save them from their own stupidity. But you can't deny, they are still so cute.
