As I type this the last of my two rats, Bree is slipping away. I came up this evening to check my email, let her run and to feed her only to find her lethargic and old lady like in the bottom of her pen. I picked her up and warmed her for a little while after discovering she wasn't already dead. She wabbles as she moves in a tight little ball... not looking well at all. God speed sweet little Bree. :(
