Hi there,
One of the reasons my buns stop eating or refusing things hard to chew like papaya treat is that they have molar spurs. This is hard to diagnose without a trip to the vet and putting them under with gas or a very very low dose of general anesthesia. If the tongue is getting irritated, or the gums, they don't want to chew or eat the food.
You need to start getting some fiber and food in her so her stomach doesn't slow down. She may get hungry enough to try to eat, but when it starts to hurt again, she'll stop and give up trying.
Critical Care by Oxbow Hay is the best, and you can get 35cc syringes at
www.rabbitstop.com or petleithwerks.com Also - there is a Critter be better formula you can use as well. If you have timothy hay pellets, you can make your own mixture by grinding them into a fine dust using a coffee grinder or food processor. Mix it with water until it's soupy enough to get through a large syringe (You can get a feeding syringe at a pet store - they have them now in the cat/kitten section for sick pets). You can also mix a little pumpkin in for flavor. OR you can crush some fennel (anise) - that stimulates the appetite. Parsley is good for digestion. You can crush up fresh greens into tiny little pieces for Jordi to lap up as well. It takes less chewing.
I also buy bene-bac pet gel (lactobacillius) to keep the good bacteria in the belly. You can get probiotic powder at the pet store or at a health store. That also works with a little mixed in with the food or water.
To continue the good treat taste with the papaya tabs (oxbow?) - crush them with a pill crusher and dissolve them in a little water. She can lap that up and it's sweet and tasty. It's a good way to get more water into her.
Stay away from the juice - you don't need it. The sugar rush isn't good when they are sick. Only use FRESH pineapple juice if a hairball is possible. But the crushed papaya/pineapple tabs from oxbow in water will do the same thing with the enzymes.
When you take Jordi to the vet, and if it is the teeth, make sure you get an antibiotic for at least 7 days. It may not look like an infection is there, but if a molar spur is pressing anywhere for any amount of time, it causes a sore and that can develop after the fact from the irritation. This happened with my Bindi. A sulfa-trimethoprim suspension is easier on the tummy than baytril suspension or injectible baytril (given in smaller doses - have your vet look it up).
If they are in enormous pain, my vet has also given me metacam - that works well, but you only want to use it for a couple of days if you have to. It can upset the tummy.
Try to stay away from motility drugs like metachlorpamide if you can. The force feeding of the timothy mush/critical care is good enough to get the belly going....only if you have a total shut down would that come into play.
One last resort is Nutracal. It's got a lot of sugar, but if it's a Sunday night and you can't get to an emergency center for your bun - this will give them a little boost which will make them feel better because it does have some nutrients that juice doesn't have. It's false energy - but I've only used it in an extreme emergency.
I'd take Jordi to the vet as soon as you can. Sporadic eating - it's a classic sign of teeth issues.
