I started my rat colony when I was up to 10 snakes. It wasn't to save money, because I expected it to cost more than buying bulk frozen, it was so I could have a constant supply for my finicky eaters who wouldn't eat frozen with any regularity.

Currently I have 3.14 breeder rats, that I have put into a rotation that produces 2 litters per week, roughly of course. I am able to get my bedding and lab block(6F) from a local horse supply store. I typically spend around 75.00 per month with them.

Now my colony does produce more rats than what I use during a typical week, so I sell my extras to other snake keepers in my area. This helps to offset my rodent costs.

Hope this helps,

John
