Really love this crate! It is well made and sturdy.  I have a 13 pound dog and debated what size to buy. I got the medium size and am glad I did.  I put a memory foam crate mat and a blanket around the edge of the crate to make it more comfortable.  It gives him enough room to be able to turn around and stretch out.  It was easy to put together and I didn't even need the directions.  I love that it has two doors and I have the option of what door I want to leave open.

I had purchased a fabric crate, from another site, and it had a smell that would not leave even though I airred it out for around 5 days.  The smell was sickening.  I don't have to deal with the smell with this crate and if you want it more "cave like" there are some great ideas for easy diy covers for wire crates on YouTube.

Pros: Well made, sturdy and easy to put together
Cons: None and expect none
