How many babies did she end up having Kelly?
That mix Becky suggested may seem like a lot but believe me it lasts a long time and you don't have to spend much really. I buy a box of store brand cereal for instance at WalMart that is identical to the brand name Total (about $4) for about $1.97. I get really great quality dog food free samples at a local pet store. A lot of it can even be the ends of your own cereal so you don't waste....my rats love the last handful or two of Banana Nut Crunch that no one around here will use up LOL. I use up a lot of leftovers on them that would otherwise get tossed out (scraps of cooked meat, bones, extra cooked pasta, stuff like that).
I love that the rat colony efficiently turns that stuff into big fat baby rats for me! Just had another female deliver a litter of 12 today and my other female is nursing her litter of 15 pups (well 13 since Malachi ate two last night LOL).
