... you don't go to the toilet because guess who's asleep on your lap, even though you're busting (like right now for example, ahem >u<)

... your partner sends you a picture of a kitten on his lap as an excuse not to do the vacuuming! nawww
... you spend the last few dollars in your bank account on cat treats instead of petrol... everyone knows you still get a few km's when the fuel light comes on!
... co-workers ask you how your cats are just as often as they ask about you, because they know you'll talk about them anyway so it's better to get it over and done with (I am the only cat person at work and I don't care)
... when you're talking about building a house, and get more excited over where the cat room will be, where to build the cat bathroom or how many catwalks, towers and ledges there will be instead of what colour to paint it.
