Why are we the only animal with the need to wipe after we go to the bathroom?

If I don't wipe once I feel the burning sensation throughout the day, but pretty much every other animal has a "no wipe" policy. do all animals feel this and ignore it or is there an actual scientific explanation for why we need (or desire) to do something that other animals do not?

Many animals prolapse their rectum when defecating while humans do not. Other animals do manually clean themselves with various methods (like licking). When defecation is complete, the animal then reduces the prolapse to normal position and and remaining fecal material is stored in the distal rectum for the next round. For humans, after defecating there may be fecal material left around the anus, which can cause irritation.
