They're not actually babies, although two of them are adolescents, full of teen-like energy that they, fortunately, take out on each other. They were called Karl and Simba, names I neither like nor could easily recall, although they are a tan, leonine color (one self and one hooded).
The third is a shy but adorable dumbo girl, with a black cap but a white chin and throat. She was named Cocoa, and I played around with names to go with hers.
Finally, we decided these three will be the Imaginary furkids, with names from Foster's Home for Imaginary Friends. Cocoa became Koko; Eduardo is perfect for the larger, shyer boy; and despite its oddness as a name for a tan rat, we decided on Bloo for the smaller, bolder brother.
Koko is afraid of people, and we're working on that. I think she's basically more friendly than Prissy is and just needs time & handling. The boys are incredibly wonderful! Their owner had to give them up because she works in a lab with myco-free medical rats, and new job rules forbid anyone working with the lab rats to have rats at home, for fear of spreading myco. You can really tell these boys were raised from babies with a lot of knowledge and love!
The boys are now in a separate cage, getting young-adult food with more protein; when they move in, the Seraglio will have seven, just about right for a double Critter Nation.
I'm sad Adam died (see earlier post), but all the rats we have now are healthy, a state to be cherished!
