Persona non grata in my mind, they're territorial and will kill a swimming dog. Interestingly Evanston, an urban area, has lots of swimming dogs. And trees. Don't know if Evanston does, but many suburbs in the area have ordinances required any tree cut down to be replaced, unless certified by the city as diseased. Now they'll have to make a BeaverLivesMatter exception. But what about the willow's lives?
I think the largest rodent is in the governor’s office.
