I once had a neighbor constantly losing track of her outdoor cat, and would wander around calling the cat by name for an hour. I relayed this obnoxious story to a nature photographer, he said kill the cat, as in shoot it. I said no. He said to buy him a plane ticket, and he'll shoot the cat.

A family member is a veterinary technician, and says outdoor cats do a lot of damage, and the cat themselves lives a shorter life. Outdoor cats should be considered the same as any stray animal or varmint and picked up by animal control, but I guess it's impractical for whatever reason.

Anyway, cats should be kept indoors, and outdoor cat owners are ignorant.
