Firstly, is the “foul smell” from poop distinctively different than territorial poops? It is natural for rabbits, especially ones not neutered/spayed, to have more territorial poops, that are sort of coated in an oil. A lot of people relate it to an onion-y smell. I have a spayed female who still poops onion-smell occasionally. If it is reminiscent of this, you don’t need to worry about the smelling poop — that’s normal.

It sounds like the health behaviors are currently there, including eating, drinking, and pooping right now, which is great. A lot of improvement from the beginning of your post. It seems like the liquidy sound may have been gas-related, since she seemed livelier after the simethicone?

The vegetables you are feeding her sound pretty typical and generally safe, but I wonder if, because of her age and when they were introduced, her gut biome may not be ready to break down all those veggies yet, and this is producing gas? If you wanted to test it out, you can eliminate all vegetables and just start with one (romaine is typically the safest one) and see if there are improvements.

Id also try cutting out everything except hay and a small amount of pellets (dont stop pellets completely, it can be difficult for the bunny tummy to absorb all the nutrients in hay only, especially if the bun is young). I’d keep giving the probiotics (the best probiotics for rabbits are saccharomyces cereviciae (brewer’s yeast) and enterococcus fascism (a type of bacterium that is highly prevalent in the healthy rabbit gut).

The sulfadim was probably in case she had coccidiosis, which is a common parasite that can be lethal in baby rabbits (because they cause ample diarrhea and rapid dehydration). Hopefully the parasite was eliminated by the sulfadim, if there was a parasite. The stomach could be upset for a while following an ordeal like that.

There are other antibiotics that can be used for suspected stomach bugs in rabbits (such as metronidazole, typically for 5 days), but you’d need a sympathetic vet to discuss treatment with and get a prescription from, of course. As you are aware, antibiotics in themselves cause disruption of the gut microbiota and must be used with great caution in rabbits.

Keep keeping a very close eye.

It seems you are seeing improvement! It can be a couple of weeks before her poop returns to normal. When my bun had a long bout of stasis last fall I took pictures of his poop daily so I could follow his progess closely without having to wonder if I was imagining things!

Its good that she hops around. Hopping around gets the intestines moving, which is why you hear the sounds then. So its not the hopping that creates the gas, the hopping just helps the gas move out of the system, which is very good. You can keep giving simethicone if you feel she needs it. It isnt absorbed into the body, it stays in the GI canal and comes out with the poop. My bun had simethicone daily for more than a month last fall.

Hopefully you will soon be able to reintroduce a little bit of fresh grass. Grass is very similar to hay and unlikely to cause stomach upset this time of year. (Spring grass is very rich, but it’s not spring in the northern hemisphere now).

Moving around can be a good thing. I remember for one of my rabbits, I forced them to move around to get their intestines moving. Humorously, he always left behind poops as he hopped…he must have been very clogged up, haha.

Any chance the grass you’re getting is from a different location or has been treated differently?

Fingers crossed she’s soon back to her normal activity level! It does sound very promising that she’s hopping around more!

Buns often gets sick quickly, in many cases because they do their utmost to hide any sign of illness until they nolonger can. Thats typical for prey animals, any sign of weakness and you risk being singled out by a predator. In your case though, the sickness really seems to have come on very suddenly though. It still takes a while to get the tummy back in good working order.

Sounds lovely to have fresh grass all year round! That also means your bun’s tummy will be used to grass all year round. The main risk with spring grass for rabbits is that they haven’t had any fresh grass all winter, and when it suddenly becomes available again they stuff themselves and their tummies can’t handle it.
