It's a decent cage, really well packaged and simple to assemble.  However, when we put our two bunnies in, it is DEFINITELY too small for an Australian and NZ bunny to live in.  They kept knocking down the first ramp, so we took that right out.  They can jump / climb to the first stage, but it is barely large enough for one bunny to sit on, let alone move about, and consequently climb up.  We are leaving the cage open for a while to see if bunnies will eventually work their way to the top, but I doubt it.  We tried leaving carrots and raisins on upper stages (their two favourite treats), but nope....not interested.
