# Add the required amount of shampoo to the toilet water, and have both lids lifted.
# Obtain the cat and soothe him while you carry him towards the bathroom.
# In one smooth movement, put the cat in the toilet and close both lids (you may need to stand on the lid so that he cannot escape). CAUTION: Do not get any part of your body too close to the edge, as his paws will be reaching out for any thing they can find.
# Flush the toilet three or four times. This provides a "power wash and rinse" which I have found to be quite effective.
# Have someone open the door to the outside and ensure that there are no people between the toilet and the outside door.
# Stand behind the toilet as far as you can, and quickly lift both lids.
# The now-clean cat will rocket out of the toilet, and run outside where he will dry himself.
