Quick question. I know some of you guys here use apple biters. My bird keeps gnawing at things that she absolutely should not be chewing at when she's out of the cage. Me getting up every 10 seconds to stop her isn't helping very much. I was wondering, is apple biters sold at pet stores? Because I'm not sure my local pet store sells those. Or would you have to get it at some place like Pick 'n' Save?
