Sometimes a bloated tummy could mean worms. I would just watch her tonight and wait until in the morning to take her in to see the vet.
My little Hootie (9 weeks) absolutely LOVES her food, too. Her tummy is rather bloated, but I think she is just fat
Hopefully it is just something like this or a result of her "air licking" and not something serious. She may be just tired and full and not feel like eating. Maybe she ate while you were gone.
Personally, I would not withhold food or water from her...she might have a hypoglocemic attack as a result. I would treat everything like normal, giving her food and water until tomorrow morning then take her to the vet. It just isn't a good idea at all the withhold food from these little guys. If she has an upset tummy, you could try giving her some plain yogurt...it is great at settling their tummies. You can give it to her plain, or if she is on hard food, you could mix some yogurt with her hard food.
Please keep us updated and let us know what the vet says in the AM.
