My resident rat is currently blocked off in the top half of the CN. I put cardboard over the closed off ramp opening to keep her from seeing the new rats but she managed to chew a hole in it anyways 😝 She seems very intrigued about her new neighbors. She basically just sits over the closed off ramp and watches and smells what's happening below. Is it too soon to let them all meet? The new rats are super skittish but that's expected for the first day.
