Is this a good deal??

Ya, that's a pretty good deal, their normal price is $14.99. And everywhere else that I know of they are $19.99.

Thx, how many do you think I need to buy? I want a 2x4 anda 1x4 loft on top?

I'd get 2 boxes. You'll probably only use about a box and 1/4 th or so of the next one for the cage, but its always nice to have extra grids around, to build a hayrack, or a tunnel or ramp or a gate or something for floortime.

Sounds good. Thx for your help.

Your welcome, good luck with the new cage. Post pics if you can when its done

will do.
