I bought this for my 3 month old Holland Lop (Solo), when I first got her, so that she would have plenty of room to be comfortable and play

Great size for my 4lb teacup

When he's locked in, he knows it down time

We actually combined two so that the pen was longer (used wooden dowels for support) and it leaves enough room for our Miniature Schnauzer to rest/play and eat without being right on top of her Richell Paw Trax Mesh Training Tray, Pink

SO easy to put together and functional

It makes a great den that puppies feel extremely comfortable in
