So I started off feeding my pastel baby a rat pup every 3 days when I first got her from the breeder. I have now upgraded her feedings to every 5 days. The problem is my local pet store, where I get my feeders do not always have large enough rat pups (sometimes their more like pinkies). So the past few weeks she has been getting mice.

Should I just find another pet store with rat pups or will mice be fine?

She is a huge piggy, should I still keep it on the 5 day cycle?

Thanks!
