thanks for all the great info! this will really help. I got 20 feeders yesterday for like $47! it is getting ridiculous. some how, i think this will save me money because about every 3 or 4 weeks I am spending that kind of money. (some of my snakes eat more than one rodent at a time.) So I think if I just buy a crap load of food and bedding etc, and get all the setups. I will be set for like 6 months free of charge. (that is saying I plan a head for this properly) thanks again for all the info!
