You bathe both cats at once? Brave woman! I do one at a time, when I do bathe them. But most cats are so good at grooming themselves that I just let them self-clean. I use a deep buckets when I bathe. I clip claws first thing, then put the two buckets in the shower, fill them with enough water to get the cat's rump wet. The buckets are useful for two reasons. One is the cat is scared, so he grips the top of the bucket when I lower him in (versus my arm) and two the buckets keep the water warmer. I have the shower hose nearby (off) and I scoop the water over the cat, getting him as wet as I can. I have also lined the bottom of the shower stall with a towel so if the cat does get away (and he is scruffed gently throughout the process) he doesn't get spooked on the slick surface and scare himself more. After he is lathered up, I place him in the second bucket which has just a little bit more water than the first. Still scruffing him, I turn on the shower hose and wash him off. I never put water or soap past their neck- keeping it away from their ears and eyes. Then I lift them out, into a waiting warmed towel that has been cycling in the dryer and towel him off.
