I bleached all the tubs and let them dry over night before putting the animals in. I have 6 original animals on this rack. What i meant was to pair my 3 normal breeders to my 3 males. Having said that we are almost at day 30 since they last shed after pairing. I cant scatter these animals around my house. I run a recording studio and all rooms have vibration from the drums other than this blocked off room, and my mom doesnt want them however if I keep them in here im OK.
