This is Momo, a mosaic chinchilla. She helped me post this necklace last night. (I'm liking my new eyeshadow, but it looks funky here. Oh well.) She's such a good helper. She nibbles on my buttons, and makes chilla-poops. If you scratch her behind the ears she makes a cute squish face. My husband and I adopted her a year and a half ago through Petfinder, which is an awesome website. My mom found her dog through them as well.
Yesterday I discovered this shop because the owner has her chinchilla in her avatar:
