Never heard of them snatching anything other than chickens or free meals from dumpsters. They can be a pain but are pretty much left be until they become a problem or hunting season whichever comes first. Have seen some cats. One was what I think was a lynx (pointy eared) when I was a kid..and one my dog was chasing a few years back it was pretty close to his size and he runs a bit over 90#s. Lucky for the dog the cat was smarter than him . It circled back behind him and went the other way. I was living in Union at the time and mentioned it to one of the oldtimers the guy told me there was a good population in the area..They are very shy. Personally I wouldn't even worry about bears or cats...It's the Wolves that could be a problem...and yes we do have Wolves here in NH..I have ran into them as far south as Strafford and Farmington. _Not_ a fun experience after dark.
