For anybody who hasnt used this stuff yet, I just wanted to let you all know its pretty darn spiffy! I have alot of animals and I have been trying to minimize my cage space because, well Ive got vivs everywhere. You all know the cost of premade rack systems can be outrageous, so I will share what I came up with that seems to work great for me. I went to Wal-mart and bought sterilite storage rack systems, I have one that has three 24in x 18in tubs cost $17.89. Right now I am useing them for some of my my leopard gecko brood stock (3 pairs) and plan to set them up for snakes shortly. The problem with the stock shelves is that the bottom of one is the top of the one below it. This makes heat tape pretty much useless. My solution to this was heat cable, I got a 14ft lenght for $21.00 this was enough to run twice the length of each container, and still have enough left to reach the outlet. I drilled small holes in the back bottom corners of each tub, looped the cable along the back wall and then down to the tubs below. I left enough slack in the cable inbetween the tubs to open and close them with ease. I am really happy with the results and will post some pics of the set-up shortly. I condensed three separate vivs into a much smaller space for about $40.00. Im still not sure about how secure this would be for my corns yet but will continue to keep you posted.
