The Tiki Hut can be filled with treats and then wood dowels are placed in front. Your bird has to get through the dowels to get to the treats. You can use a single row of dowels or a double row to increase the difficulty level. Each Tiki Hut comes with 45 dowels and extra packs of dowels can be purchased should they be needed. The Tiki Hut is very tough and dishwasher safe too.
