Can a mouse flatten its body?

Mice and rats have somewhat collapsible rib cages. Their ribs have a greater capacity to flex than most other mammals, enabling them to flatten themselves temporarily to squeeze through narrow cracks. If a mouse can fit its head through a space, the rest of its body can squeeze through as well.

Can mice collapse their bones?

The Collapsible Skeleton Myth For years a rumor has circulated that rodents have collapsible skeletons which allow them to squeeze through tight spaces. This is not true. The skeleton of a mouse accommodates its lifestyle, a good deal of which is taken up by burrowing for food and safety.
