I don't mind cleaning up your hairballs, but please don't sit there bursting with pride and a look that says:
"I feeled bad in my tumtum and then I made bleah and now I feels ALL BETTER! I am so smart! S-M-R-T smart! Yay for Cats!"
It is an accomplishment (of sorts) to tag 8 different places in the house (including 3 floors and 2 stairwells) while horking up one single hairball, but it's not really one you should be proud of.
