Not a cage, more the frame on my Cat. Just like the Soundgarden track, hence the misleading subject. Anyway, it's stained brown at the welds, and in fact was like that when I bought it. No bubbling or anything nasty. Yet. Do TADTS? Should I take pre-emptive action, or just get it sorted if and when it gets worse. If it's not going to fall apart for ten years, I'm not that bothered.
