Feeding their massive litters definitely takes it out of them. We like to control our environment so we separate our mothers until weaning. When they come out to play they spend 2 hrs eating yogurt, kitten food or scrambled eggs plus wrestling. I find that playtimes allow them to keep muscle tone as well as baby fat. This vigor makes them very willing to breed. In some cases we can throw our friendly moms in with younger rats and they tend to jump around happily whilst pouncing everyone like they just snorted crack. Maybe they enjoy the mature company lol. Or they just so damed tired of hearing constant high pitched squeaking when they try to shift sleeping positions.
