At the end of the day, you must accept that we were all placed on to this planet by "something" for a purpose. Whichever you believe that something to be, I am not getting into a religious discussion as I would defy the rules of this forum myself, but I believe every living being, be it human or animal has a purpose, and are part of a natural ecolgic food chain. Rats and mice are cute too, but they are also considered a vermin, and foxes gets rid of a lot of them, so they are in that circle too.

As Keithblade RIGHTLY said their natural rural habitat has been destroyed and they are been forced out. So they are now as urban as the common cat. Do we cull stray cats? No we don't, but in London we do cull a large number of deer in Richmond Park every season, I used to live very close to that park and in the dead of night you could hear 100's of gun shots, and they use the best marksmen, so you can make sure that if you hear 100 shots that's a 100 dead deer.
