I would. You are probably paying more for rats than the cost of breeding.I mathed out per 4 weeks, and 20 breeders, I use no more than 1 large bag of pine(5$) less than one bag of tractor supply dog food(14$) and supplement with food scraps from home. I was previously paying 3$ per small rat. The only problem then is do you have enough animals to eat all the rats.
