Oh nice! You could hide it under an upturned flower pot or bury it. That might keep things from taking it.
Something will find it, I can just about guarantee that. Dogs, cats, especially hungry squirrels, corvids, random “varmint” class critters, anything you can think of. Heck, large ants will dismantle it and steal the tiny bones. Put a flowerpot over it, with the hole uncovered to let flies in, and anchor the flowerpot firmly. I don’t advise burying it, mouse bones are too tiny and hard to recover.
