Hello, I am so exicted about trying to build one of these cages. I have been viewing this site for little over a week. I thought I was doing everything correct with the enviroment for them and after viewing this I felt like a bad parent. I have purchased the cubes and the coroplast (very easy to find). my problem is, is that I am not a handy person I can ruin anything, but I'm determined on this one. I have 3 dogs and 2 cats and 4 small children so I need to make the cage completely enclosed. I would like to put doors on the first level and second level and also a door that flips up on the first and second level. I was viewing chumley's cage and I really like that one. I don't know how to put hinges or exactly what to ask for in the store. I'm going to be attempting building the cage this Friday 2-6-04. I will not rest until I finish it. I have 5 pigs and they are in desperate need of a new home. Well actually four until I spay the female, then it will be 5 all together.
