Food doesn't stay in the anus. Food stays in the stomach. Other stuff stays in the anus.

A rat is a deuterostome. Deuterostomes are a group of animals that includes vertebrates like rats, as well as other animals such as humans. They are characterized by the way their embryos develop, which involves the blastopore forming into the anus first.
Disclaimer: I saw this question in the Mice and Rats category; I'm not a mouse so I'm only speaking here as a rat. I would prefer if you didn't use peppermint oil on my anus. But if you would like to use it on your own anus do so at your own risk.

Rats poop through their anus, expelling waste material from their digestive system. Their excretory process involves the formation of feces in the large intestine, where water is absorbed and solid waste is produced. Rats typically excrete small, dark pellets that are firm in texture.
Rats eat anything. That is why they have lasted so long.
