The vet just called and all of Feeby's test came back - all well within normal range!! He even said there was nothing even remotely close to bordering a high/low reading. So, as he said, "she is looking good"! No UTI either!!! I am very happy about this, but now we will have to continue to ponder the arthritic aspect - or wait to see if she improves on her own. Maybe like human seniors, she is just having a bit of a bad spell with her 'old joints/bones'?
