Fecal pellets are quite dry--u can break them apart with yr fingernails. Not so bad to have loose on a floor. But cecotrophs are mushy and they'd get stuck in fur, as in yuck. I wonder if the bunns r not eating up their cecotrophs.
I don't regard bunny poops as being all that dirty. They are hard dry little pellets, and when I scooped up a bunch in the palm of my hand and smelled them, they had a herb like smell with a onion/sulfur overtone. The important gut bacteria for a rabbit is the bacteria that transforms cellulose into glucose. If you get this bacteria on your hand in then in your mouth, there is no problem.
Cecotrophs: Vegeterian animals like cows, etc, regurgitate the contents of their stomach that performs the cellulose to glucose transformation. Chewing their cud is the description. They rechew the stomach contents and reswallow. For rabbits, the cellulose to glucose transforming stomach is the Cecum...it's located at the juncture of the small intestine and large intestine. In humans, it's a vestigle organ known as the appendix. For rabbits, they cannot regurgitate the contents of the Cecum..the contents have to pass out through the large intestine and then out the rectum. A healthy rabbit will know when the Cecum pellet (Cecotroph) is coming and will immediately bend over and eat it. The Cecum pellet is not poop....it's regurgitated stomach contents. For the first several years of bunny ownership, I didn't even know this. It was only when, as an older bunny, she developed spinal stenosis and couldn't bend over to eat the cecum pellet that we knew. The cecum pellet is a problem. Because bunnies don't regard it as poop, they will leave it anywhere if they can't eat it. This can smoosh up in the hair around their rectum, also stain carpets and cloth furniture. For Bunny, we started giving her Metacam, an anelgesic, that relieved back pain, and she went back to eating her cecum pellets.
My Flemmish babies are white haired. If you look at there butts, they are perfectly clean...perfectly white. They are eating their cecum pellets without problem.
Cecum pellets contain liver enzymes. They look black, but if bunny is eating a lot of green vegies, you can see that they are really dark green. Because of the liver enzymes, if you smoosh up a cecum pellet in your fingers, it has a nasty vomitous smell to it. But the bunnies eat these things!!!
