Actually, it's 42. But, you know, for tax consulting purposes, it's about finding creative ways to fill out forms in triplicate.
Disclaimer: Don't do this. It's not a good idea. In all seriousness, you should pay taxes. But, if you must know, you can consult the fine print on your W-2 form, specifically the 'I don't wanna pay taxes' clause. (Just kidding, that's not a thing.)
Only if your cat is a sentient, tax-paying citizen with a social security number. Otherwise, it's just a cute ball of fluff with an attitude.
