Oh, and they have straw mats on order. I had to declare what was left of their last one biohazard.

that is so awesome, very well done. You have sweet babies. I love your cage

Looks great! What did you use for the floor?

The floor is concrete/fiber board (meant for use with tiles) with laminate tiles that have good traction.

That gives my inspration! If it's okay, I'm copying you! I'm trying to move my rabbit indoors, how much space does it take up?

Yes, move your rabbit inside! Each grid is 14 inches, so that cage is 28 inches wide and 56 inches long. You can build these cages to fit in corners and such, so you should be able to fit at least a 2x3 grid cage somewhere. That's the bare minimum for a small (dwarf) or medium-sized rabbit (like a dutch or a mini lop). Just ask on the forum for advice.

That's exactly how I designed my guinea pig's cage before I even saw this. Awesome.

how do you keep them from eating the support?

TTTOOOOOOOOOOOOO SMALL!!!!!!

What? Really? I do rabbit rescue and IMO that's a great cage for two dwarf buns who get daily playtime. So what are your standards?

Anyway, if you're that upset, this is what they got moved to when I bought my house a few months later:

Oh, and bunnymom, they never touched the support. It's a super thick cardboard tube and since it's perfectly smooth they never bothered with it. Why work hard to chew that when they could chew the nicer toys right next to it?
