My roommate and I recently gave our kitty a bath to rid her of fleas. Our initial strategy was to take her into the bathroom, close the door, and fill the tub with water just enough to cover her paws... she was not cool with that, so then we tried the sink, which she was also not cool with. Ultimately, I ended up removing everything from my bathroom counter, and using a small plastic cup I just sort of poured warm water onto my cat while she wandered around on top of the counter (my roommate held her as still as she could). We massaged the shampoo into her fur, and then just kept pouring cups of water on her and rubbing it out until she was clean. The bathroom was very, very wet, but it worked -- afterwards, she was clean, soft, and flea-free! Remember to wrap your kitty in a towel when the bath is over... for some reason, cats find towels comforting.
Anyway, you may have already bathed your cat at this point, but if not, good luck!
