When I was a kid, we had a cat who was a master at exploitation. This cat basically used all 9 of his lives at some point. He got run over, set on fire (he was chasing fireworks and caught a jumping jack that went off under him), and more. Worst of all, he got shot with a .22 in his shoulder. The vet told us he probably used a couple of his lives that day, but he survived.
Anyway, he limped around for a while after we brought him home from that injury. He eventually got better, and was back to walking normally. Anyway, when he wanted attention after that, he would start limping around. He especially liked doing this when new people were visiting.
