I name my pets, but if i was a breeder or a rescue I might not. I do have a small problem with my little CDTs. One had a slightly deformed shell when I got her so I named her Shelbi. The other was more friendly and would bob his head when I petted him/her so became Bob. Now Shelbi's shell is no longer deformed and I cant tell them apart. They were tiny when I got them. BTW~ My old car had a name, but my new one does not yet.
