I'm probably a little over-cautious in this regard, but it seems like petstores are hazardous places with all of the people AND animal traffic that go through them. Does anyone else advocate washing new parrot toys before letting birds play with them? I'm sincerely afraid my birds will catch some sickness from unwashed toys (or anything new in their cage, for that matter).
Or am I doing my birds a disservice by not exposing them to new potential-bacteria and letting them build up an immunity? (I've read that kids develop more allergies and lower immunities if they don't have such exposure.)
