Coyote eats cat in West Roxbury

These cyotes have been migrating east for decades. Not quite the same thing as an invasive species, which is typically so completely alien to the ecosystem that its introduction pushes out other species that can't compete (e.g. zebra mussles ejected from the bilge of tankers into the Great Lakes). The cyotes that we have are actually filling the open niche of top predator left vacant by the wolf, which we killed off long ago, and which ate all of the animals the cyotes now do. Although I agree that cyotes who make their home in urban environments and start posing a danger to humans should be put down or relocated, their migration east is not "invasive" and they don't need to be rubbed out (even if such a thing could be done considering that more continue to migrate).
