I have no idea what he was being fed at Huntingdon Animal Shelter, but with me he was fed Nutro dry. He loved canned food as well, but was never fed any of the recalled stuff.

His first adoptive home, where he got the UTI (if that's what it was...), was feeding him crap (Friskies or Purina... sorry just don't think it's great stuff). Have no idea what he was being fed at the 2nd home.

What causes CRF?? Is it diet and stress??
