My new cage for Wrangler arrives today. After all i've read about toxicity, etc, I want to make sure I am properly sterilizing/neutralizing? the cage before he goes in. He uses his beak a lot...to slide down the bars, pull himself up, and generally navigate his way around. Do i clean it with bleach? Do i rinse it with vinegar? what strength? how much? how long? sunshine exposure? Its a new cage, but I still want to make sure it's safe for him. Also, perches. Is it essential to have one going the full width or length of the cage? Should dowels be wrapped in vetwrap to make them less hard? ANy type of perch (other than dowel) that is NOT good for ekkies?
