Are you serious? Would you be happy to find shit all over your brand new carpet, or in fact any carpet, ruined?
To be frank, I wish we could just get rid of the cats now. I like them, but I dislike finding shit and the smell of piss in my house much more than I like selfish cats who will "let you" pat them when they feel like it, or rub themselves up against you all lovey dovey when there's a tin of Whiskers in your hand.
Obviously I have a conscience and realise we'll be stuck with these cats for at least another ten years now, unless they get run over or eaten by a dog or some other fortunate event occurs.
