Are you sure it is blood and not red pee? Rabbits urine ranges in color from yellow to red depending on diet. If it wasn't just red pee take your rabbit to a vet who specializes in small animals
No rabbits eat their feces, although all rabbits eat cecotropes. Rabbits have two kinds of droppings: feces, and cecotropes. Baby rabbits that aren't weaned yet eat their mother's cecotropes; once they're weaned, they eat their own cecotropes.
Cecotropy is the process by which rabbits will reingest part of their feces by eating them directly from the rectum. Rabbits only ingest the soft "night" feces or cecotrophs. Hence the word Cecotropy.
Yes, you must let your rabbits eat their own feces because it's an important part of their digestive system. Rabbits need to eat their feces in order to get all the nutrients they need out of their food. If a rabbit is prevented from eating it's feces, it will become ill. (Actually, to be technical, rabbits don't eat their feces at all: they eat their cecotropes, although it looks like they're eating their feces.) See the related questions below for more details.

Yes, rabbits do indeed eat their own feces. Rabbits are vegans, and like most vegan animals, their digestive tract is not long enough to fully extract the nutrients from what they eat. So they will eat it again. Deer tend to like to eat rabbit feces too, so if you find a pile of rabbit feces, there may be deer nearby.
There are no vitamins or nutrients in rabbit feces, but there are many nutrients in their cecotropes, and when rabbits eat their cecotropes, it does look like they're eating their feces. See the related question below for more details.
In a way, they can. When they don't poop for 24 hours they...it's fatal.
Blood in the feces is not a specific disease - it is a symptom that can indicate any of several diseases. In younger dogs, blood in the feces is more likely to indicate either intestinal parasites or a gastrointestinal infection. In older dogs, the odds of cancer resulting in blood in the feces rises.
It could be any number of things from worms, to infection, to organ failure. If your cat has blood in its feces, take it to the vet immediately.
Are you meaning soft feces??? Every rabbit has a soft night time feces. Most eat it before you ever see it. It aides in their digestion of foods.
Many animals leave small round droppings of feces. Rabbits, deer, goats, chinchillas and most types of bugs leave feces fitting this description.
It means blood in the feces that is not visibly apparent.
