I don't blame you for worrying, Liz. I'd call too. The only time I remember Honey acting in a similar fashion was after her surgery and she had to be boarded for a few days and developed a bladder infection. I don't think she "went" enough in the kennel and the infection was a result of that. I do remember that medication cleared her up quickly and that Dr. Robinson said this was not uncommon. Talk with the vet. You know her habits better than anyone and if you are worried, then the vet needs to know about it.
Good luck! I'm off to take Bennie Cockatiel to his new "mom", Amber (CamCamPup) this afternoon, but I'll check back in tonight.
