Powder coating has seriously taken over the industry of bird cages, yet this kind of feature might be tricky. For example, paint is usually poisonous. Parrots tend to chew bars. With time, they develop all kinds of syndromes before dying. Unfortunately, many manufacturers promise safe and nontoxic coating, yet you cannot check. Therefore, if you truly care about your bird’s health, opt for a stainless steel cage or a wrought iron one. You can also find wrought iron flight cage models. These materials are quite common due to being safe for birds. Moreover, they are solid enough to face tear and wear.
