The cat cage is fine more for kittens than bigger cats.  It took quite some time to set up, esp. the wheels.  Rolls fairly easily, but wire gauge could be stronger.  Also, the ledge(s) that are included were tricky to set up.  They had a tendency  to tilt forward and could be a bit more generous in size.  I put 2 of them next to one another so the cat could stretch out a little. There was a space at the top of the cage where the side and top pieces met.  I fastened a stationary 'clip' to keep the seams pinched together.  Now the cat has access to be out of the cage.  Only kept her confined for maybe 10 days or so.  Cage is probably best for recovering cats or temporary lodging or young kittens,etc.     C.F.,  New Jersey
