some rat questions

i honestly dont know how old it is though. it's 53 grams, would that put it at four weeks?

I would assume near 4 but without knowing what they have been eating and how often etc... This may help you more: If the rat is 1.5 - 2 times the size of an adult moust...you should be able tell the difference. The "sack" will be prominently hanging.

ooh ok, then "howard" is deffinitely a girl. i think i'm just gonna feed him to zulu
