My dwarf bunny fits well in this cage, and has room to hop around. A standard size rabbit would be too large to make it up the ramp to the second level. My only complaint would be the misleading "ease of assembly". It's more realistically a two-person project, and some muscle required. But the cage itself makes a great home, the only improvement I might ask for, would be for a bit of a barrier along where the floor and walls meet, in order for litter and feces to not be so easily pushed to the outside.
