Just back from the vet and Charlie just a bit of inflammation that showed in his urine but no sugar or crystals or anything else. The vet did say she felt something in the abdomen but thought it might be a piece of hard stool so I had them do an xray to make sure it wasn't a bladder stone. Good news it was not and they said he is so small the xray showed his heart and everything else looks good too
They gave him an anti for what they believe is the very beginning of a slight infection. What a relief. Charlie has been so healthy his whole life that it scared me to think there might have been something seriously wrong.
Thank you again for your help.
