Dipping in purely because I like this topic:
Oddly, not in North America. We have native panthers/cougars/puma/bobcats etcetera but no small cats. In fact, there was basically nothing in the niche of small ambush predator at all, the small native predators are all rundown hunters like coyotes and various weasels or generalists like raccoons have bad matchups against small birds. Cats are probably more unreasonably destructive to native species in NA than anyone will ever be able to quantify, more on the scale of "rats introduced to small South Pacific Islands" than something like the brown Bahama anoles displacing the native Carolina anoles in Florida.
