So I currently have two litters of rats. One 6 day old litter (7 pups) and one two day old litter (8 pups). At first the mother of the older litter was doing very well, obsessivly nesting and caring for babies, keeping weight on and such. But I've noticed that she's lost a lot of weight, she's very boney now. Her babies also seem colder than usual, and seem a bit skinny today. She also managed to cut her nose somehow. I'm wondering if it would be better to foster this litter to the mother with the younger litter, so that the first mother can recover and put weight on again. She is currently eating 23 percent rat pellets, along with some dog food ( 32 percent protein, maybe a few pieces per day) and some sunflower seeds (Introduced today). Picture of the two litters below, the hooded is the older litter, the light one is from the two day old litter to show size.
