Katie did an excellent job with the goody bags at the conference. There was a Chinese finger toy inside each bag. You put a nut or a small acorn inside of these and Mine love ripping them apart to find the treat. My only problem is that Boo, pictured here, thinks that they are all hers. She brutally takes them from the other squirrels and won't share. They can also be zip tied to the cage wire once you have the treats shoved in them.
This is a great idea. Way to go Katie! I think you can get these at the Oriental Trading Post???
