I was pretty close with my guestimate. Chomper weighed 936g empty today.

@ BWB- I can't think of any issues with feeding your carpets rats when they're young but I kept on mice fuzzys and hoppers until they were big enough for rat fuzzys or pups. I think they benefit more from prey with fur and a more developed bone structure. I try to get my snakes off of pinkys ASAP.
