Normal rabbit poop is firm, pea-sized, and rolls across the floor when your rabbit hops out of its box. Your rabbit is telling you they’re feeling good. This bunny poop (fecal pellets) shouldn’t be rock hard and a pellet should fall apart when you squish it between your fingers.
Yes, this language is very up close and personal.
Hindgut fermentation is the digestive process of herbivores with a simple single-chambered stomach. This is the case with your rabbit. This process breaks down their high-fiber diet into digestible material. When the food is digested in the small intestine during the first trip through your rabbit, it comes out as a fecal pellet.
Here’s a little plot twist though. There is another type of rabbit poop that is normal. This type looks like a tiny bunch of grapes and is called cecotropes (cecal pellets).
Have you ever noticed your rabbit eating poop? It was these cecotropes and it’s normal and healthy! Thank goodness right, your bunny eating poop is normal…
These pellets come from non-digestible plant material. They get to travel through your rabbit's digestive system a second time. They get re-ingested in the caecum. The caecum is home to enzymes and bacteria that transform this indigestible fiber into nutrients that your rabbit’s body can absorb.
So when you see your rabbit eating their poop they are actually being very resourceful. Leave no nutrients left behind…
It’s normal to not see many cecotropes. Rabbits like to eat cecotropes as soon as they are produced. They don’t save them for later. If you are seeing a lot of them left behind in your bun’s litter box then they might be eating too many sweets or carb-rich treats. In this case, your bunny is telling you they need more hay in their life.
The types of rabbit poop you see tell you if your rabbit is getting the right diet, and if your bun is digesting it well.
