This is simple.
Put both lids of the toilet
up.
Add 1/8 cup of pet shampoo to the
water in the bowl
In one smooth movement, put the cat in the
toilet and close the lid
The cat will self agitate and make
ample suds. Never mind the noise that comes from the toilet the cat is
actually enjoying this.
Flush the toilet three of four
times. This provides a power-wash and rinse.
Have someone open the front door of
your home. Be sure that there are no people between the bathroom and the
front door.
Stand behind the toilet as far as
you can and quickly lift the lid
The cat will rocket out of the
toilet, streak through the bathroom and run outside where he will dry
himself
Both the commode and the sat will
be sparkling clean.

Sincerely,
The dog.
