Having done rescuing for too many years, and needing to cage my newcomers until they've had shots, testing etc. I've had more than my share of stinky kittens! I think they smell wonderful when I rub them with a Downy fabric sheet for the dryer. It's dry, so no water involved, is non-toxic in case they lick it, and makes them smell so fresh. I've had to resort to bathing some however, and try to work fast. Most cat shampoos are fine to use on their heads,(read directions) but they shouldn't get water in their ears. I do a quick shampoo across the head, and cuff my head over ears, and eyes to rinse, while leaning their nose toward the ground. Needless to say, most times, they give up due to shock of being wet, so not too many fighters. Chip on the otherhand is my resident nutcase black Siamese cat who loves to roll in the potty. But he times it till after I'm done scooping thankfully!
