Did a back search, and couldnt really find any... To me, It just seems ungodly expensive to raise rats (maybe a little less for mice) than to just breed.

I spent 34 dollars buying 8 weeks worth of food for 1bp 2baby corns and 1 adult corn, as compared to the 41 dollars i spent on two bags of rat chow and a big rat wheel for my boyfriend's rat and my new future breeder boy.

Could anyone help me out figuring if this is cost effecient?
Say for 1 adult bp its 1.50/rat totalling 6$ per month.
1 bag of Nutriphase was about 5$ (2 lb bag) that will last me... i have no idea how long...

Is there anyone that 1) knows how long a 2lb bag would last 1.1 pair of rats and then how long the babies would take to reach size to feed a smallish adult ball python?
I can work on the rest of the math myself.

In 3 years I will have 3 snakes eating large mice, two eating small rats, 3 eating weanlings, and probably one more maybe eating large mice/small rats. Would you suggest my own colony or buying pk?
