Overgrown claws is a mutation where the lion's claws grow extremely fast until the point where they are unable to ever detract their claws. After the claws are unable to detract they are unable to grow anymore which leaves it at a forever state of having the claws stretched out. The claws can cause many problems such as it getting snagged of things on the ground. This causes a few health defects but the lions still regularly have a normal life span.
