I got some rat feeders at the White Plains Reptile Expo yesterday, and they are way bigger than i am used to seeing. The rat fuzzies i got are the size of rat pups and the rat pups i got are the size of small rats??? What were they feeding these things??? The rat pups i am used to getting weigh about 22 grams, these weigh 32 grams. Any reason why such a differance??? Just curious...
