Humans (nor animals) need to "clean" on the inside of the rectum which is inside the body. The anus, the orifice (opening) to the outside simply needs wiped, and washed with soap, water, and rinsed with water.
This is the animal equivalent of using toilet paper! Animals can't hold a sheet of toilet paper to clean their bottoms so they use their tongues.
i believe they do
No. They clean bedrooms.
Clean?!?
No
So they wont smell.

I don't think that there is an exact amount of wipes each time to use for your butt to be considered clean. Just use as many wipes as you need to make your butt clean. You may want to take a quick look at the wipe once in a while to see how much more you should wipe.
go to the doctor
Escherichia coli for example.
