Bella sleeps funky, too. Many times up on her back letting legs just fly wherever. In her crate, she does quite a few flops in the night. We have it probably bigger than she needs, but is handling it well. But boy, when she repositions herself, sounds like she's propelling across the crate and crashes into the other side. Never wakes HER up, that I know of while she's doing this, but the first few times scared the bejesus out of hubby and I, . A few times I've had to check on her to see if she was OK. Quite the racket indeed!
