Hello from Arizona--- Joe my dear Tuxedo has been to the vet more than I can tell you---however, the latest is he is on Purina DM and is losing weight - 2-3 pounds (he was a steady 11 pounds) - he is 16 and alert, but rather lethargic and now has low appetite. He really isn't diabetic, since going on Purina DM canned food. - but that food has no carbs, and of course they will lose weight. HELP! Thank YOU all!
