Need more assvice

Nope, this isn't about the adoption and how to keep myself from going nutso-but I have another factor in my life that may push me over the edge as well. My, make that Dave's; 12 year old cat, who has never scratched any furniture or done anything ill-behaved, has suddenly decided to start pissing and crapping on our couches. This morning was about the 6th or 7th time in the past two months. I don't know what brought it on, there is no new stresses for him to be concerned about, the dog is gone, no kids to taunt him (yet). Seriously, David is so lucky it's his cat, because if mine did that (and my perfect little Higgins would never ever do anything wrong), I would give him a new home. Under the wheel of my car. Any idea what a pain in the arse it is to remove the cushion covers, febreeze the crap out of the cushions, leave them in the sun, wash the covers 10 times and repeat twice a week? This is why I am a dog person, you can't exactly punish a cat like you can a dog and have them "get it". Not to mention the deep 8 inch scar on my thigh I have from trying to pick him up. Evil little creature. Yes, I know Ronnie, cat soup does sound like a good idea.
