Again that’s the humans fault for destroying habitat, should we ban development as well?
Ideally yes, and I'm not a big fan of current human reproduction rates either (just because people
want kids, doesn't mean we
need so many of them...).
My neighbours dog was fond of killing/maiming possums regularly. He was also fond laying ribbons of blindness causing turds on the public nature strip and parks (excellent owners). Also sent the neighbours kid to hospital with an infected bite.
Like you say, bad owners. The slight distinction I make with dogs vs. cats, is dogs don't generally leave the boundaries of their home property. To my mind, if a wild animal makes itself accessible to being eaten/killed by a dog, it's kind of natural selection, but a cat's speed, agility, climbing ability and stealthiness that enables it to go past the boundaries of its home changes the balance and makes it a predator, whereas dogs (generally speaking) can't climb and are just opportunistic killers if something strays within reach. Probably more of an issue on rural/forested properties, but not really a problem in metro areas.
Would you want to be kept indoors your entire life against your will?
No, but I also don't walk about killing things for entertainment. There's also been a bunch of studies done that show there's basically no ill effects on a cat's health by being kept indoors. Relatively speaking a house (or even a reasonable apartment) is a huge area for a cat to play in compared to a human. It would be like having a small shopping-centre worth of space to yourself.
Despite my responses, I do understand your feelings. Obviously, mine just differ some.
