Jessica, thanks for the nice comments about my girl! She was one of my first pet rats and is already a year old. She is like a hot water bottle, especially when she snuggles up to my neck. You can really feel their warmth. As far as breeding goes, I would do it if you wanted them for pets, but not for feeders. She had 3 normal litters, of 13, 15, and 14. Then when her 4th litter came, it was only 4 pinkies. From that point on, she never had more than 7 babies in a litter. Her average is 5, sometimes it'll be 6 or 4, but usually she'll have 5. She is also a baby eater. If I don't take the pinks away, they will slowly disappear over time. She's very quick about it I guess. I've never seen her do it, or found any evidence, but I know its her doing it, because the other female never has any missing babies. Its kind of cool now though, I got that new girl, the grey one. Well after my hairless girl had her latest litter, the grey one adopted them and raised them herself. So this time, 4 actually have made it past pinky stage. One advantage of hairless is that she is not susceptible to mites. My male has mites, but she doesn't. They can't hide in any hair on her. I've tried all kinds of treatment to get rid of them, but its an ongoing battle.
