And not the Louis Theroux one!
It was on TV a few years ago (at a complete guess, maybe 4 years ago, but I could be making that up). It was about exotic animals being kept as pets, I think, and something happened whereby these animals escaped and were loose in a town in America.
Ideally, I would love to be able to watch this again somehow, although i’m not convinced it will be available anywhere, even if anyone manages to come up with the name! But it would at least put my mind at rest to know what it was!
