Could be a sign of Stasis or a parasite, but it could also be the lettuce if you feed her more than she eats her hay and pellets. Your bun will need a trip to the vet for a few tests if taking lettuce out of her diet doesnt show any improvements 

Lettuce and salad in general are very little caloric and contain a lot of water, so they’re not of much nourishment if not used as a “filler” food in between hay and pellets.If she can stomach it, I would suggest to move on to celery or fennel, that have more calories and fiber. They shouldn’t upset her because they’re well tolerated even by kits, you could try to give her small softer pieces and see how it goes.

Do keep us updated, good luck! I really hope she is fine

If she’s losing weight with no other symptom, you could give her a little bit more pellets. Lettuce have very few calories.

But it is worrying when somebody (not just a bun) is loosing weight for “no reason”. Try and weigh her every week or twice a week and note down the weight. If she continues losing weight, make a vet appt.

I think the others have good suggestions.

One thing I would say is – has she been molting recently? George and Charlie are looking a bit thinner at the moment (though their spine feels perfectly healthy) and I’m pretty sure it’s all the hair they’ve been shedding.

Another reason a bunny can lose weight, and this is quite common in older buns (over 6), is a dental problem. My Bindi sometimes loses weight when he needs his molar spurs trimmed.

You could try to buy quality hay pellets, that are just pressed hay without extra additives. Maybe she’ll find them intriguing to eat! They would also keep her teeth in check, so that she will avoid spurs problems. I’m based in Europe so I can’t be specific about any brand if you’re outside EU. Maybe Oxbow produces them?

If she has a sensitive stomach and she’s molting it could be she’s having a bit of trouble with the fur, make sure you’re brushing/plucking out her dead hair daily (or as much as she’ll let you without getting stressed), it will help her a ton ^^ Do keep us updated!

That really is a significant weight-loss

Please keep us updated. Sending her so many healing ((((vibes))))

That is a drastic weight loss, I wonder if it could be intestinal parasites. Hoping your vet can figure something out for her.

I hope you get a quick answer to the cause of her weight loss and a plan to get your bunny’s weight stabilized.

I hope they find out what is causing the weight loss. I too think it could be parasites (((((vibes)))))

I suggest getting some bloodwork done if the weight situation continues. That’s usually my vet’s second go-to after the teeth are ruled out.

We’re keeping our fingers crossed for the meds to work!!

Emiline, I’m so very sorry to hear this. It seems e cuniculi was the right diagnosis. I’m sorry the meds didn’t help, but they don’t always, it’s a devious parasite -as I know you are well aware.

Thank you for the update.

Binky free, sweet little bunny girl.

I’m so very sorry for your loss.

((((Binky Free)))))

I am so sorry for the loss of your sweet girl, Emeline.

I’m so sorry. This is so sad, Sending you lots of hugs.

For my own knowledge, how did your bunny get it in the first place and it came back?

Great insight, thank you
