It’s a 3D printed design that encloses a cardboard tube (ie toilet paper roll) so I can fill the tube with Oxbow dry pellets; she then shreds the cardboard to get to the food. It usually takes about 10 minutes of dedicated work to get through the cardboard and then another 20 minutes of tossing the shredded remains around to get all the pellets out. Good for those shredding and foraging instincts!
