Found another rattle - catalytic converter

[Controller23]

I’ve been getting an intermittent rattle at random speeds and rpm… forever. Finally crawled under it to find it. It’s the catalytic converter. Sounds like something is rolling around inside it. Would this be something that might be covered under the drive train warranty? I have 50k miles on my truck. So many rattles on this truck it angers me. Sorry the vid is so short but that’s what it sounds like

Yes it would be. Didn't see the video but I suspect that cat has gone bad

Iirc, the catalytic converter is covered under federal emissions warranty.  Iirc, that's up to 80,000 miles.  I forget the timeframe, so I may also be incorrect.  Not going to look it up myself.  Google is your friend on that one.
