Here are some links to a few small critter related sites.

Chinchilla Ranch Brand Directory -- A very useful page maintained by Chinchillabreeders.org that provides a search for the ranch brands for most chinchilla ranches. If you've ever gotten a pedigree and weren't sure what bloodlines it represents, this is a great place to check!
Chinchillas.org -- Lots of chinchilla links and resources, including a forum.
Hedgehog Color Site -- A very in-depth look at hedgehog color genetics. This is the best site I've seen about the subject so far.
Little Critter Sites -- Huge directory of small pet information, including breeders and sellers of pets and supplies.
