I would prefer to sell this in the Houston area, but I guess I would consider shipping too.
I have a slightly used but in excellent condition metal collapsable dog kennel crate with the plastic tray bottom that slides out. The dimensions are approximately 36" D x 24" W x 24" H.
Since I did not personally buy this one (was a gift), I don't know the actual brand or original cost. Comparing to other ones I've seen at places like Petsmart and Petco, they run about $79 - $100.
I am willing to sell for $40. Please email me if interested, then come take a look at it before you buy. I think you'll see that this is a good deal.
