Where did you get the washing machine drain pan and what size's do they come in. Like I said before, I live in an apt. and can only do so many things with my set-ups. I am pretty much stuck with my 2x2x4 cages and am trying to find a way to be able to mist/humidify the cages while I am at work (4:00 a.m. to 7:00 p.m.). If I could find a pan that would sit in the bottom of the cage, be able to support the weight of the live plants and collect the water until I got home to drain it myself then that would be great. The only other solution would to be to build my own cages and put a drainage system in. Unfortunately, I don't have the time, money, or tools to complete a project like this. There has to be someone out there that has a similiar set-up and can help me!!!!!!
