Can a cat’s broken bone heal on its own?

A cat’s mild fracture may heal on its own. The bone has a periosteum that promotes healing, so a mild fracture can self-repair.

But if the femur, pelvis, or spine is broken, letting it heal naturally may lead to malunion, which affects movement. For a serious fracture, take the cat to a vet promptly. Also, to prevent deformity, it is worth getting an X-ray at the vet even for moderate cases.
