Dexter likes shredding paper, cardboard and soft wood, but not the harder wooden blocks. He likes to empty out boxes and those polycarb foraging balls, which I stuff full (very tight) with shredded paper. He will kill anything made of softer plastic, like the wiffle ball type toys. And, he has completely killed one of those small sneakers, too! I didn't know if he loved it or hated it, but it didn't last long LOL.
He's a real "thinker" and is as likely to spend his time figuring out how to loosen and unscrew the quick link a new toy is hanging from as he is destroying the toy itself. I've found I can't use the smaller pear shaped links because he opens them right up and I'm afraid he's going to get one caught around his lower beak. He also likes to unwind chains from a split ring (like a key ring) and untie knots. I can spend an hour making a twisted, knotted toy with leather cords and stainless chains and rings and and he will disassemble/untangle it in half the time. Punk.
