Obviously Arf has never read how to wash your cat and clean your toilet in one simple operation.
Requires two people, dish soap or toilet cleaner, welding gloves
Preparation:
Wait until cat is asleep in the sun.
Add large volume of soap to toilet, clear path, wedge bathroom door properly.
Have helper stand by at nearest exterior door
Don welding gloves, elbow length preferred. May consider full welding PPE, especially if you have a leather apron and autoshade helmet .
Vigorously seize cat
After approaching pitch cat headlong into toilet and slam lid down in a single motion. This is the do or die moment of the operation. Failure is not an option. There may be opportunity here to clean those nasty old welding gloves as well.
Hold lid down while cat washes himself, and cleans your toilet.
After a suitable interval, hit the rinse button. Hit it again.
Once you feel the cat and toilet are well rinsed and free of soap, call out to your helper to open the exterior door and stand clear.
Raise toilet lid, examine toilet to see if properly cleaned.
DX PPE, and if necessary, retrieve cleaned welding gloves and hang them up to dry.
