My skinny rescue rats have a new favorite food. Chicken dinner baby food. I diluted it slightly with warm water and put it on a plate and they are happily lapping it up! YAY Half of the cage is over a heating pad and they have lots of soft cloth to curl up in. Cage is covered on three sides, since they are hairless and so skinny I want to keep them warm. They don't feel cold to the touch anymore. I'm so happy, they just might make it.
