Joker, my mother's orange tabby, has been in multiple accidents during his nine lives. Until a few years ago, he'd always behave at the vets. Finally, he'd had enough. I dropped him off at the vet's to get patched up while I went to an appointment. When I returned to get him, there was a note: "Let owner get him out of the kennel." He'd shredded a vet and an assistant.
