I think my indian ringneck might like something like that (downsized for Pookie of course). Will have to go look at that site again and see how this was made. She only likes paper-y or shredder/ crunchy things, no wood.
Making the toy could not be easier. I only used about 50 coffee filters I made four or five cuts in the filters -- in stacks of 10 for easy scissoring. Then I just used a knife to pierce the stack of filters and then pushed the sisal rope through the knife slit. The last step was separating the filters and kind of scrunching them as if you were making crepe paper flowers. Dude took a day or two to get used to it and then he completely loved it -- shred city. Enjoy.
