I have one 1000 + grams female ball and realized breeding mice will be cheaper. I use to buy but at 2.50 a mouse being the cheapest ( for dinky little mice ) and 3.99 for a bit larger mice at Petco. Mice are around 20 grams so 5 mice every week or two is pretty expensive and the female bp's grow quite large. So one female ball python eating live makes breeding mice worth it cost wise. That is once you have all the equiment you need, like enclosure, water bottle, food, chew stuff, and houses, and spinner toy, which I now have. Any tips by pm or forum on breeding mice feeders will be appreciated. Thanks. - Steve
