See, you can be a cat AND a dog lover, Ricky Gervais has just showcased how this is possible. He loves all animals, and the only reason he hasn't got a dog is because he travels so much. He can actually keep a cat because a cat doesn't really care if you bugger off as long as you've deposited enough food.
For you see, 90% of cats' behaviour is food motivated (while we're at it, 99% of stats are made up on the spot), they'll be fine rubbing off a scratching post and scaling your shelves for a short stint, while a dog wants to be with you. Always.
For those desperately seeking more Gervais, here he is trying to sell an "upside down blue bucket." Or, in his mind, something a hell of a lot more sordid. And uncomfortable.
