Here's part of the article:
Unformed Cecotropes: Mushy or Runny Stool Perhaps the most common complaint regarding rabbit health is the problem
of mushy or runny stool sticking to the bunny's anal area and creating a nasty, stinky mess. In most cases (in adult rabbits, at least),
this mass is made of poorly formed cecotropes that have the consistency of toothpaste, rather than the normal form of bunched, squishy pellets.
The cecum is a delicately balanced ecosystem.
If the intestine is moving too slowly, or if the rabbit is getting a diet too rich in digestible carbohydrates and too low in crude fiber, the complex population of bacteria in the cecum can become "unbalanced." This condition is known as cecal dysbiosis. Cecal dysbiosis means that the beneficial bacteria (e.g.,
Bacteroides spp. and a variety of others, including archaeans) are outcompeted and outnumbered by less desirable inhabitants such as yeast (a fungus, usually
Saccharomycopsis sp.) or even very harmful bacteria such as
Clostridium spp., related to the ones that cause tetanus and botulism.
A rabbit suffering from cecal dysbiosis will produce cecotropes that are mushy, pasty or even liquid. They are usually quite foul-smelling, and often stick to the bunny's back end in great, nasty clumps.
These unformed cecotropes are not a primary disease, however. They are a symptom of a disorder somewhere in the bunny's system. In order to solve the runny stool problem, the underlying cause must be addressed.

Found another article (posted about cecal in another thread). I think Olivia might be suffering from this. The crasins could have done this. Has she been eating her hay? If she's hot, it might have put her off her hay and cause this.
Here's more of what the article said about dietary.
Dietary Problems
- Incorrect Diet
- Rabbits, like horses and cattle, are strict herbivores. The rabbit intestine--and its normal bacterial flora--has evolved to feed almost exclusively on grass and herbs. >br> Does your rabbit get starchy treats such as oatmeal, crackers, bread or sweets? Some rabbits with very sensitive intestines can suffer from runny cecotropes even from commercial pellets. Fruit, as healthy as it is for humans, can be too much of a good thing for rabbits. The high level of sugar and starch in table fruit makes them too rich for a bunny except as a very small, occasional treat. A diet too rich in digestible starch is one of the most common causes of runny cecotropes in companion rabbits.
- Insufficient Indigestible Fiber
- A rabbit should be fed unlimited grass hay, such as timothy, brome, wheat or oat. Alfalfa hay is too rich in calories and protein for daily feeding. A rabbit who cannot nibble constantly on high-fiber grass or hay may suffer from a lack of tonus in the gut muscles. Normal peristalsis (muscular movements that push food through the gut) may become sluggish. This causes the passage of food through the cecum to slow down, and the normal rate of bacterial "flushing" from the cecum is disrupted, promoting cecal dysbiosis. The high fiber content of grass hay also helps to "dilute" the starch of other dietary items, and helps to provide a healthy intestinal environment. A complete and healthy diet is truly key to preventing intestinal problems such as cecal dysbiosis (and its associated mushy stool).
Hope this helps a bit.
