They certainly DID damage him. GILL brought him most of the way a week ago today, and Monday I took Koi in and got confirmation he had a UTI, crystals, mites, fleas, and his curled up foot was infected. At long last, the UTI is MUCH better, and the last 2 nights he's peed in his adapted litterbox. He runs amok during the day, and even found his way downstairs yesterday!! He'd never done stairs before.
