@duglop Our cats even love the short tube tunnels but their favorite thing remains boxes to hide in & pounce from. Whenever we get big, sturdy boxes we save them to replace the one they've managed to trash, cut at least 2 entrances in them & tape the flaps closed. We call it their castle & they love getting a new one. They bring their toys in there to play with. Sometimes, unaware the castle is occupied, we will go to move it a bit & 2-3 cats leap out, upset about their nap being interrupted 😆
