It sounds like she’s basically OK if you are working with your vet about her weight. How long ago did you change her diet? I ask because even a slight change in a bunny’s diet can cause a temporary change in their digestion, so the mushy poopies may be a result of that.

Many bunnies cannot reach their cecals, or get them stuck in odd places. You might just keep a moist paper towel handy when you check her and help clean off her rear end a bit to keep her comfortable. If it gets mushier, like diarrhea, then call your vet back. If not, her poopies should firm up in a day or two.

What was her health report like from the shelter? I can’t recall what she’s had checked out so far. Sometimes coccodia(sp?) can cause messy poop. You may want her tested. Giving hay only and some rolled oats can help dry up messy poop too. Have you seen her cleaning herself? Does she look like she struggles with the task?

Well, timothy hay is what is so good for them to keep their guts moving in a healthy way, so it’s possible that since she didn’t have any before it’s working with a vengeance. I would try weaning her off of her old pellets now and stick with the oxbow and hay and see if it’s less messy today. Since it’s the weekend, watch for improvement and again, if it’s worse during the week, call the vet.

Since she was not getting timothy hay before, and now she is, I think that you are going to see a lot of progress over the next few days and weeks as she converts to a healthy diet. I have definitely heard of bunnies not being able to reach their cecals, I wonder if she is able to reach any of them, or none of them. If she can’t get to any of them, if you get them off her bum with a paper towel, you might want to leave the paper towel in the litterbox in case she decides to eat them (yea, I know, a liiiitle gross )

I agree that if the mushy poop continues when she has been on just hay and timothy pellets for a little while, then she should probably go to the vet because neither of those things should really cause any mushy poops.

How much did Marshmellow weigh when you got her?  a weight loss of 5 ounces in a week seems quick- as that is about a 1/3 pound.

My last bunny I adopted was on junky pellets and limited hay and no veggies-  and it took a bit for his poops to firm up- they were softer than usual when I first brought him home- probably due to diet change and stress of a new environment.  I did get a fecal checked to make sure there were no intestinal parasites- so that is a good thing that the vet tested for that.

LOL OK that makes sense-I’m like five ounces in a week!! That must be the holllywood diet LOL

Overweight buns do have trouble reaching their cecals (as well, cleaning that whole area too!) but since you have just noticied this I’d think she can reach the cecals (otherwise she would always have sticky poopies) I bet she’s just adjusting to the new and improved diet. Like pam said, keep watch for any worsening but I bet you’ll see improvement from the great diet :

Sonn, that’s just plain rolled oats by the way, not the instant kind. Be careful with how much too, they’re probably fattening!

I have used oat bran in place of rolled oats, or a mixture of the two together to reduce calories and increase fiber. Make sure to give it in a shallow dish as some rabbits inhale some of the dust if it is given in a deeper type of bowl.
