I don’t really have any advice on what could be going on, but I just wanted to bump this thread up for you, so somebody who might have more knowledge on this matter than me, might be able to see this thread and give you some advice.
I hope all goes well at the vet appointment, please keep us updated!

She could certainly have an underlying illness that is leading to the weight loss, even an internal parasite that may be taking some the nutrients from her food away from her. Hopefully the vet can give you some more insight. Until then it might be worth feeding her a little more than normal to try to encourage some weight gain.

Weight loss and mushy poops are the two signs my senior lop exhibits when he needs his molars trimmed. If your bun doesn’t have her teeth checked regularly, at her age and with those symptoms, I would def have the vet check out her teeth.

Good luck at your appointment!

Oh no…! I hope it is treatable.. Sending warm thoughts toward you and your bun

I’m sorry but I haven’t gone through anything like that just wanted to send you wishes.

I hope the bloodwork and testing sheds some hope/insight on the situation. Luna sends vibes ((((Wilbur)))). As for the cecal stealing, the timing might depend on the bun? For Luna, she always produces cecals whenever I brush her (no idea why) and also right before bed.

Nothing to add, unfortunately, but wanted to send along some ((((Positive Vibes)))). I know waiting for test results is hard.

Awww, poor Wilbur Here’s hoping for some test results that have a simple solution. ((((Wilbur))))

Regarding the cecals, I know with Luna if I see her eating one, often she’ll go down and grab a second one after. Otherwise, sometimes I notice that she’ll curl her back more and shuffle a back leg forward before she reaches down. I rarely see Apollo eating cecals, I think he naturally produces less of them.

Have the hair trimmings, baby powder, and ointment helped at all? I hope she gets better soon; it sounds like you’re doing everything you can for her .

If it helps at all, the probiotic I have comes as a powder, Jerseygirl actually suggested to me that I sprinkle it on wet veggies. So it’s also possible you could crush a probiotic up and sprinkle the powder over the top of a serving of wet veggies. Mine have no hesitation at eating their sprinkled veggies.

I’m glad there were no abnormal cells detected, but I do wish you had more of a solid answer of what was going on. At least she is showing improvement

Goodness me, I’m sorry to hear about her heart. I hope that the ultrasound can provide you with more answers when you are able to have it done.

Apart from the added oats and increasing pellets a little, I’m not sure what to suggest for weight gain.

(((Wilbur)))

Tried researching weight gain for rabbits and some people suggest adding a bit of afalfa to their diet 30 percent afalfa 70 percent usual hay because it’s higher in protien I guess?

Or afalfa pellets apparently are a thing too and if you could find those might be easier to feed separately from your other bun then loose hay

And apparently canned pumpkin is a good food (like plain pumpkin not the pie stuff) for weight gain and you could probably mix the oats in that too if she doesn’t like them plain. But I looked on regular rabbit food lists and I didn’t see any that mentioned pumpkin so I don’t know about that one

Found a old fourm post about pumpkin consumption

I really hope your bun gets well soon! I am sorry to hear about her heart… hope they find a medication that helps her

Im sorry about Totoro. Sorry if you had mentioned his passing elsewhere, I hadn’t seen it. Binky Free, Beautiful!
Im also sorry to hear about your cat. : ( Sounds like you have your hands full with that and Wilbur’s condition also. Sending positive health {{{vibes}}} and anti-stress {{{vibes}}} your way.

There wasn’t evidence of arthritis or anything from the x-rays? Not eating cecals and then getting a gut imbalance along with having a sludgy bladder can be things like arthritis or spinal issue..

I would have said gradual weightloss isn’t too unusual in older rabbits and her having lost a bond mate may have contributed some but now with the test results, it does seem clear she has a bit more going on. {{{Wilbur!}}} Hopefully the diurectic will help manage the heart issue. 

Albumin was low and there was evidence of abnormal liver function. There was also red cell regeneration and it idicated a stress or infection response. Still waiting for the results on the fluid taken from her hind legs. She’s had 3 doses of antibiotic so far and yesterday her poops were much drier and more formed. She even had a couple normal poops!

Yay for some normal poops!
What antibiotic did the vet put her on? Im wondering about hepatic coccidiosis also. Was a fecal test done in the end? I think the eggs can be detected in a fresh sample, but they don’t spore for a couple of days so I wonder if testing fresh and less fresh poop would be worthwhile? I don’t know the protocol for testing for this form of coccidiosis.
It just came to mind because of the blood results, the weightloss and “watery feel of the cecum”.

Weightloss occurs with this condition due to intereference with the rabbits ability to absorb nutrients. Although, older rabbits don’t absorb them as efficiently either. Since you are having an ultrasound done, it would reveal if the liver is looking enlarged and help rule out this condition. I suppose the x-rays would have shown this too, if present?

Any suggestions for food to fatten her up? I’m going to try giving her oats per the vet’s suggestion. I just have to be very careful about making sure Fig doesn’t eat her special foods.

I’ve heard of calf-manna helping for weight gain. It has higher protein content. https://www.mannapro.com/products/rabbit/rabbits

Also: I’m supposed to steal cecals from Fig and feed them to Wilbur. Anyone have experience stealing them from rabbits? I have no idea if you can even figure out when they’re going to produce them.

Tricky!
They are supposed to produce cec’s about 4-5hrs after eating (??) but rabbits kinda eat all the time. lol. But if you do a morning or evening feed of pelleted food, maybe start to take not about 4hrs after (if possible!) to see if there is a regular time they are eating cecals. Getting spares is another story! Im not sure how you’d do that unless Fig is in the habit of dropping a few. If you do collect some, try offer them as is to Wilbur. Otherwise, try wrapping in a leaf of something green or even basil, which would mask the smell if she’s put off by his cecals. Even though it looks like rabbits chew on cecals, they are supposed to go to the stomach intact. The mucus coating starts to break down there then the nutrient absorbed in the lower intestine. I’ve often wonder if the chewing action is not actually biting the cecal pellets and is about getting the saliva to start the breakdown process. idk!
