Will Oreo eat anything at all? Sometimes I think my bunnies are uncomfortable and in stasis, and then I offer them some veggies or a small treat and they jump up
I also have a bunny who often gets gas and acts similar to how you are describing. I use the simethicone that comes in tablets (I think it does have a mint flavor). I crush one tablet between two spoons, and use a small syringe to put some water in it. I mix a small amount of water a simethicone together on the spoon, and then draw it up with the syringe, and give it to my bunny. Then I try to get him to move around a bit. He is around 5 lbs. and has not had a problem with the amount of 1 tablet. Not quite all of it usually gets into the syringe, so it is about 3/4 of a tablet.
If the simethicone is not helping, it could definitely possibly be stasis. If it is stasis, it is important to address it as quickly as possible, the earlier you get her to the vet the better. The vet can do things like administer subQ fluids, and pain meds, and medications that will improve her stomach motility, and it will be more effective if you get those things to her as soon as possible.
I hope Oreo is feeling better soon!
