PrairiePurrs, be glad you weren't in process of cleaning the toilet when some kitty decided to take a swim!
When my Molly and Kit were still pretty young, one after the other they came in and dove right into the toilet bowl as I was cleaning.
Obviously, my concern was to get each one of them and attempt to rinse them off to get the cleaning stuff off of them. Thankfully I use the more safer-for-the-environment kinds of cleaners and only their feet/legs actually went into the toilet bowl.
