Ive just gone through this discussion with a possible glider Daddy on the phone... it has been a heavily discussed topic here in the past... but I havent seen it recently on the board for new(er) owners...
Consider it a preventative measure... :)
Here are a few links I found online regarding possible heavy metal poisoning (caused by galvanized cages)...
sounds like vet. care is the majority of the treatment once again...
much of this is on birds, but I use the 'bird-safe' rule for my gliders...
