Well Geoffrey is home from his scan. There is something up with his right kidney, it looks very thickened and the middle bit looks very small and uneven. There aren't any obvious lumps or cysts, but something is clearly not right. Left one looks fine and bladder looks fine. My vet is on holiday for a fortnight now so we have 3 weeks worth of antibiotics and hope that it is 'just' a particularly nasty kidney infection, I will do another urine sample in a couple of weeks when she is back, unless of course I am concerned in the meantime. If this doesn't make any difference then he will probably need a biopsy, so please everyone cross fingers that the longer course of antibiotics work well!
Poor Geoffrey has shaved sides too. She said they can normally just do it from a shaved belly but because he has...additional padding...they weren't getting a good enough view.
He's glad to be home for now!
