Johanna, you are too funny!!
My brother in laws mom has about 15 - 20 cats. (Some indoors and some outdoors ALL have been spayed/neutered/microchipped/ and are current on their shots, she takes 3 to the vet a month!!! )
She scoops 3 times a day!!! Once in the morning, comes home on her lunch and scoops and in the evening!!!! Now that is a clean-a-holic!!!
