Those nutrea were lucky to find you
On one of my trips to Louisiana, I took a hokey swap tour in an airboat(it was actually a lot of fun - the son of the tour operator took my SO and me on a twilight tour...but I digress), and nutria were everywhere. The waters are teeming with them. They are absoultely seen as pests there.
Ages ago, there was a market for their pelts but that bottomed out. Some folks tried to use 'em in their cooking but from what I've been told, they're not tasty and require lots of seasoning (not a problem in LA cooking though!).
I'm glad the little guys have found a good home. They are kind of cute (the clacking sound they make with their teeth is sort of freaky though).
I'll look in the news for stories about a nutria population explosion in Oregon
