We just got a new girl! Her name is Cookies & Cream Decaf, Cookie for short. Intros are going perfect! Cookie is super young maybe 2 weeks idk for sure because shes a feeder rat rescue, and Latte is about 2 months. I took the neutral territory method and there already in the cage with an igloo and a hammock ( Latte isn't a hammock rat though) and there's been no fights, basically just force grooming from Latte and a little from Cookie. I'll send pics when I can!
