Yesterday I was going to try feeding a rat pup to my BP for the first time. However the rat pups I found in the only store in my area that has them were smaller than the mouse I usually feed my snake. So my question is should I stick with the mouse or try feeding 2 rat pups to my guy. I've heard the pups have more nutrition than the mice. The pet store clerk said the sizes of the rats are very inconsistent, there really isn't anyone one in my area who sells live. So now I am conflicted...
