Like all TomCat models, the FatCat attaches to the tree very easily using adjustable slide-in hooks and pins. Each TomCat model utilizes cat like teeth to dig into the bark. As with the TomCat II, you can choose to sit facing the tree, or by using the slide out seat, sit with your back to the tree. The seat can be easily adjusted by hand, by using the easy to grip thumb screws. FatCat maximum weight limit is 300 lbs.
