I saw one in an add for a store that handles closeouts, and they had one for about $14 more, but had less features.  You get more for your money here and compare this company with other online pet furniture.  I did and I came back here to get good quality and more for my money.

The instructions were better with this one.  This one gives you some brief written info to read before you assemble.  It also uses step by step pictorials, whereas the larger unit had one big pictorial and was somewhat difficult to follow with so much info shown all crammed together.
