The first thing that catches my eye when mounted is that it's crate is just big enough for a kitten. If the cat is too fat, I highly recommend because it would have too little space inside. Fairly easy to fit and strong plastic I think it can hold out long enough. The side access door is iron impossible to open from the inside (even for a clever cat) If, however, the cat (like mine) did not enter through the side door, there is always the door above which is larger.
