When I took Bokka into the vets yesterday. Dr. Unapproved vendor surprised. He said powder coated cages are 100% fine and I shouldn't worry about zinc and lead. He says the chances that someone's bird would get zinc poisoning from their cage is so small most vets would ask if they have eaten or have access to zinc type toys(black rubber, bells, chains) before thinking the cage is the culprit. I thought this very interesting. What does everyone's vets say on this? I'm just curious. As for the longest time I have beat myself up for not being able to provide SS cages, its on my "one day" list.
