"Pro: Its wheeled base allows you to roll it away to vacuum under.
Con: This product is extremely poorly made. The wire sides and top are held in place with small and brittle plastic L-connectors. Half did not properly fit and broke on construction. The remainder have broken within a month. Further the plastic ramp broke the first time the rabbit jumped on it! Lastly the shelf is a two piece sliding fit plastic tray. The rabbit, although far from a "large" one, likes to jump up on it and the stress has caused it to seriously bow and crack. And the cage is less than three months old.
We are holding the cage together with "bailing wire." (Wire ties that come with plastic bags.) Rabbit is starting to figure out just what they are and how to undo it!"
