I'm sorry to hear about Blackberry!
Ferrets are too funny. Snowflake doesn't really like being a ferret. Let's see, she's been a polar bear, a mountain goat, a gecko, a werewolf, a dinosaur I believe and countless other animals.
She's very funny though. If you're not paying attention to her, she'll run up and nip you, usually the feet, and then she'll run away.
She always starts fights with Napoleon and then when he gets upset, she'll cry for me to get him off of her. She's such a little baby sometimes
