how old do rats need to be to get to a medium size 130grams and large size 270 grams?
i am talking about rats that get at most 450 grams when very old. also if you are so helpfull to reply specify if you are talking about males or females becasue the males grow much faster.
( i never bothered keeping records or rats.... i am starting now but need this data asap.... the reason is i never needed rat and sold all i produced but now i need for a boa i got so i need to know when the next "cluth" or medium or large rats is availble so i know how much to sell and still have for my boas.. thanks
a reallll lot
