ok kila... litttle harsh, they are asking, we should answer...

Anyway I know exactly what cage you're talking about and its a pretty good size for one tiel but not two.
I tried to search the directions that pretty bird wrot eup for making your own cage but I cant find them. Basically you can use firring strips (untreated) black hardware netting and any large tray you can find. Make the base out of plywood, use the wood firring stips to make the supports for the mesh, and staple the mesh on the outside, then put more firring strips on the corners (if you so wish, thats more of a cosmetic thing) you can make it any size you want and just attach legs to it for a stand.
