I have 3 snakes. 1 is certainly on hopper mice, next week will be moved up to small adult mice (12.5 grams). My other 2 are on 20 gram mice and growing fast. I was looking into getting rat pups (20-29 grams) but I think they will grow right through those and might have to supplement the rat pups with something smaller to get the proper feeding. Should I upgrade buy weaned rats instead? Buying from rodentpro so they come in 25 packs which is why I'm asking.
