This came up in the Raccoon thread, and I thought there were enough strong opinions to really get everybody going. Let me start with one of those opinions: Indoor cats are a waste of everything, and should be put down or put outside. I've had cats ever since I was very young, and they've always gone in or out when they wanted to, providing that someone was there to open the door. They've always hunted, kept the house and property free of ground pests. I find that almost 100% of indoor only cats are fat, lazy, pathetic examples of their species whose existence is mostly just to piss on things, ruin furniture, and make lonely people feel less lonely and look more pathetic. "They don't live as long outside." True. So what? They reproduce like rabbits. Let them live a short, excellent life doing what they were born to do; what no creature on this planet does better than them: Hunt. (Besides that, if you find a cat cunning and strong enough to stay alive for 5+ years outside, It'll probably be alive much longer than that, and is worth 1000 indoor cats. "The Vet bill is higher." Why are you spending that much money on a creature that costs nothing to replace? Get it worm meds and the standard shots and after that If a raccoon tears its belly open or the neighbor backs over it in his truck or its kidneys fail from eating too much rodent intestine, let it die and get a new one. Begin.
