I'm just wondering, what are the disadvantages and advantages to breeding your own rats/mice vs. buying F/T? I honestly thought it was much more expensive to switch to breeding your own because you have to pay for bedding, food, extra tubs and such. But, it looks like that that's not the case. Is it not worth breeding your own if you have have about 15-20 snakes? How much money do you actually save while breeding your own? Thanks!
