My Top Ten suggestions:
#10.) I've learned the hard way that you should put the soap in the toilet before tossing in the cat.
#9.) And I also suggest holding the lid shut from the side, rather than the front.
#8.) One should have more than one cat, for each toilet, for about once a month is as often as you can safely catch the cat, for this job.
#7.) All breakable items should be removed from the top of sinks, vanities, tanks, etc. prior to starting the actual cleaning process.
#6.) 'Good' towels, washcloths, etc. should not be left hanging on the towel racks.
#5.) The bathroom door needs to be open for the entire process, lest the cat feel 'trapped' after the cleaning, and one receive the full displeasure of the cat. (Remember, the cat can climb you, just as easily as the shower curtain, which should itself already be removed from the bathroom.)
#4.) Safety Goggles are highly recommended.
#3.) A good supply of bandages, band-aids, and general first-aid supplies should be in the medicine cabinet prior to commencing the cleaning procedure.
#2.) A cell or otherwise portable phone should be easily available, with 9-1-1 on speed dial. (Ideally, one should have another nearby, with the phone already in hand.)
And the #1 suggestion is to "Be careful, but still quick with your actions!" This is not the time for slow and deliberate motions.

P.S. [Edited to add] One should definitely consider having very loud music playing, for the benefit of any nearby, 'overly sensitive' neighbors, especially any PC, 'PETA' types.
