They don't actually do anything. The ferret just shoos him away with his back to the corner and uses the bathroom for him. I ended up using them as rigging for other things. The best way I've found to keep your kids from going around corners is to put fabric in the corners. They love to snuggle up in it and fall asleep. So tie some fabric in the corner where they go in, and if you don't have access to fabric, an old shirt is very effective too!
