Well hubby is using Clay Davenports instructions on

http://www.arbreptiles.com/cages/rat_rack/ratrack.shtml

only I think he is going to use 1/2 x 1/2 wire because we already have some and use 2 x 4s for main frame.
But I assume the home depot pan with hole would be fine with this.
Hes also going to re enforce the bottoms with slats just to be safe like Clay advises.

I might have him just build a 5 pan one as I am not so sure about the 6th one being so high. I think it might be hard to get into even with a little step ladder but I will check it out and we will decide.

Hubbys making me take it slow so he is only building one rack right now and I will get a pan or two of ASFs and then have a pan for male rats and then fill what I have left up with groups of 2 or 3 females. I plan to get smaller ones so that I can handle them and make them at least hand friendly so it will proably be a few months before I can even think of breeding and then I will have him make me another rack at least to hold babies once we are at that point.
I think I am going to try keeping the females together to start with and see how it goes and if I really get into it I will have him build me a maternity ward rack. Gota go baby steps.
Its hard for me as I go in full throttle usually so we will see.

Well once again I sooooo very much appreciate all the input and help you guys have given me.
Soooo Thank You, Thank You, Thank You
