From my own personal experience, I find the best way to bathe my cats is to get into the bathtub with them. Yeah, yeah, I know it sounds gross, but it's really not.

I put about 3 inches of water in the tub. I put the cat in front of me, facing away from me. That gives you ALOT more control over the cat. Use a cup to wet the cat. Lather, rinse and towel dry!!
