Clouds doesn't seem to be a chewer. He's got a eucalyptus tree, natural perches, a wooden mini-gym and we've tried several shredding toys but he doesn't seem to get any chewing urge. Likewise, he completely ignores his cuttlebones and mineral bell.
I've got heaps of pinecones so could...
I still had some cork left and wanted to do something for Mila to chew up. So I took some of the already destroyed willow sticks from the ground and knotted them on the end of a rope.
I sew up the cork to a few smaller pieces.
Drilled some holes in them,put them on the rope and done!
