Cat lovers and dog lovers are different people I think. Sort of like the difference between a white wine lover and a red wine lover (or a Bush lover versus a Sadam lover....see? I can bring politics into ANY arena!)
So, you think cats are selfish, hairy less-than-beasts who are worthless shits.
Well, let me tell you, I'll take any one of my four cats over your dog any day!

They are loyal.
They wait for me to come home from work. They have personality. I don't have to take them out every six hours of my life to let them piddle, they don't make any noise and they don't rub their WET nose all up and down my clean legs when I get out of the shower or if I've got a skirt on!
No embarrassing snout up the crotch in front of people either. Owners that let their dogs do this to women have about as much common sense as George W Bush!
They don't bark at shadows or squirrels in the middle of the night AND you can actually have a life over a weekend by not having to board them out.

Here kitty, kitty.........
