I'm a complete newbie cockatiel/bird owner, so I'm not sure what to put in my teil Blue's cage. He has 2 wooden perches, a swing, a little toy hamburger sponge thing, food and water holders and a cuttlebone. And a treat stick and a spray millet. Is their anything else you think he'd enjoy? He LOVES shiny things if that helps .The cage is very roomy, so space really isn't an issue. Also, do you rotate the toys?
