It’s empty in here!
As soon as I had put the tower together my six cats tested it out. There are times when the tower is fully occupied and one cat in particular really likes using the scratch board on the side. It’s stable, easily moved and takes up very little space.
Got this for my two black kittens 1st Birthday and they absolutely love it. So does my ginger Tom. Highly recommended, very sturdy and easy to build.
