Also I really hate that pets, particularly cats, kill a big amount of spiders, birds, lizards, bees, and all those very useful creatures, (useful compared to pets). With 1 billion+ pets, it's an issue, and many cats go outside. It's like a 5% larger human footprint, when you consider also all the care/food brought to them, completely unnecessary

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.
Catch the cat and release it 50 miles away
Cats are menace. They kill a billion birds yearly. IIRC, 2/3rds of cats are feral. Cat owners who let their cat outside are perpetuating the problem.
My preferred solution to the cat problem is coyotes.
