The boys love their Fångst. They have one hanging in the house and second hanging in their outside kennel. We put toys in the upper levels, which entices the boys to jump and climb the Fångst in an attempt to knock the toys out. They are pretty skilled at getting the glitter balls out without even getting into the different levels. The first few days of the Fångst were real fun because they had trouble getting into the bottom level, it is free hanging/swinging. Everytime they tried to jump in, it would swing away. There was much time spent with the front legs and head inside and the back legs running around, swinging the entire Fångst in a big circle. The boys have since figured out the process of getting in. Now it is the site of many energetic battles.
