Blood in your stool can be a sign of a serious disorder. WebMD is a good resource for information. However, your ordure being red could be a symptom of something I find disgusting, but otherwise completely harmless.

NOTE: I tried as hard as I could to use as many synonyms for feces. Some I didn't use are bodily waste, droppings, pooh, poo, manure, dung, bowel movement, number two, and doo-doo. I also didn't to use any words like sheisse, merde, dreck, and govno from other languages. The reader is invited to submit their own in the comments.
