Well, things are basically unchanged.

Grady did a 10 day course of Clavamox, combined with Valium and the pain med. A week ago today, 6 days after completing the abx, he spent the better part of the day at the Vet. They were finally able to aspirate some urine. Results: gross hematuria - no infection and no crystals, low specific gravity so the kidneys are doing their job. She did an abdominal x-ray that showed nothing out of the ordinary.

Next step is an abdominal ultrasound. Probably up at MSU Vet School. I think we'll wait on that until after our trip to Virginia that begins in 10 days.

Grady is not in any obvious discomfort, eats and sleeps and plays just as he always does.

Idiopathic cystitis normally resolves with or without treatment in a couple of weeks. We're way past that point, and he still has the hematuria. It's a mystery.
