I built the first one of these for a customer's cats to eat on so the dogs wouldn't get into their food. It worked great and the cats all have their place on the tree. I have made and sold more to those who use them for various reasons. One was used as a flower display stand. I make them to order.The size is whatever will work best for the customer. This one stands 46" tall. The base starts with a disc brake rotor for weight and stability. The metal is from a stockpile of old metal that was used for another reason first and now cut and welded into this tree The wood was cut and refinished from old oak pallets.
