We love this little crate.  We got it for our little 3 lb. Maltese and she loves it.  It is much nicer than the plastic crates and we even keep it in the living room.  I love the castors on it and the fact that you can take the top of if your wish (I do this if I am cleaning it out) and still have a side door for my little girl to use.

Pros: I was easy to assemble and the simulated wood looks so nice.
Cons: None
