We often read stories about the amazing adaptability of animals. They endure pain, but they do not wallow in self-pity. A disabled animal will do what it must do to get on with life using what it has. A four-legged animal can get around pretty well on three legs, as I learned when our border collie lost one. In these stories I posted at mental_floss, four cats learned to get around pretty well with even less than three.
