I like Peanut and Lucky. I find that it helps to wait a few days after you have him to see his personality. My Muffin was going to be named Lacey at first, but she didn't respond to it. I called her Lil Muffin in a cutsey way...and her ears perked up and she ran over to me......she's been Muffin ever since.
I never would have thought to name her Muffin before that.
