Before getting into thoughts, a general PSA that if your rabbit has not pooped or eaten in 12 hours, that is considered an emergency and she should go back to the vet ASAP. Also, even though vet offices are busy (especially now), don’t hesitate to call and report new symptoms/concerns that you may have as the provider who directly examined your rabbit may have much more valuable insights on what can be expected.

The molar spurs can be a valid explanation for what’s going on, so it’s good that you have a visit set — if possible, getting one sooner is better as rabbit teeth don’t stop growing and the growth can be quite rapid. Sometimes you can contact the vet office and asked to be called when there’s a cancellation. She is eating hay, which is actually a phenomenal sign as that is what is going to keep her GI in the best state possible. If she is not drinking water out of a bowl, you can extra wet veggies so she gets increased hydration from there.

If she is not eating pellets, I’d supplement a little CC or pellet mash to her diet so she’s getting more nutrition than just the hay-veggie-water diet (plus the mixture would be hydrating too).

All this being said, I assume the first vet confirmed that there is no blockage/obstruction/risk of bloat, so she is probably pretty constipated, and it’s hard to poop with all that going on. You can try a tummy massage/hind-lifting to see if that helps: https://www.youtube.com/watch?v=LbyC6CWbm5M&t=1s&ab_channel=Howcast … personally the lifting of the hind quarters works wonders with my Wick in his recent bad gas episode.

If it is teeth discomfort, something to potentially try and encourage more eating is cutting the hay to a shorter length. From my personal observation (with my Wick whose teeth are not great), hay of long length is very effortful to eat because he (Wick) will spend literally 2 minutes moving the hay in his mouth, inching his lips and positioning the hay strand so he can start eating it at the end, as opposed to just chewing it wherever he grabs it. When he feels dental discomfort, he just gives up and doesn’t eat anything unless I cut it up as short, narrow strips, including veggies!

If she’s up again and munching hay, you don’t need to be crazy worried -but she must poop, or you should contact your vet again.

I think she purred out of pleasure when you pet her -a rabbit can chop its teeth out of pain, but if a bun is in that much pain, there will be other signs as well, such as sitting in a stiff upright position or actively pressing the tummy against the floor -like a human doing push-ups without managing to keep the back straight (you’ll have to imagine this).

Its great that she’s munching on hay. If she eats more when you hand-feed her, do  hand-feed her. If she drinks “new” water only, its good of you can renew her water often. It could very well be that colder water helps relieve mouth pain.

Dental spurs can fully explain all this  and her age also supports dental spurs as the cause. Until you get her in for a dental burr she should get pain relief (meloxicam) and you’ll probably need to support feed her critical care a few times per day. Some buns will eat CC from a plate, especially if you mix it with something yummy like canned unsweetened pumpkin (not pie filling, just plain pumpkin). Its obviously best if she eats as much as possible on her own, but if she doesnt, you should syringe feed to keep her in best possible shape for when she’s going under for the burr.
