Soft, runny, or mushy poop in rabbits
What this sign can mean and when to act, from House Rabbit Society and RWAF guidance. This is general information, not a diagnosis.
What you noticed is worth a vet's eyes soon. Rabbits are good at hiding when something is wrong, so it's best to have your exotic vet take a look before anything has a chance to progress. Book a routine appointment in the next day or two, and call sooner if anything gets worse.
What it can mean
Soft, runny, or mushy droppings can be associated with a diet too high in sugar or starch, cecal dysbiosis (an imbalance in the gut bacteria), or eating too many fresh vegetables at once. It can also be a sign the rabbit is not eating their cecotropes (the soft night droppings that are a normal part of rabbit digestion). A vet can identify the cause and advise on diet adjustments.
