I am hoping to get some help, my cat was recently diagnosed with diabetes and due to a history of severe asthma..(which is now controlled with atopica for cats) he was prednisone for several years. I wasn't aware of the damage if would cause until we switched him to Atopica. He currently take 2.5 each morning of Atopica and when he was diagnosed with diabetes Saturday the vet put him on Novalin N(1.5) twice a day. He currently eats prescription MD glucose management food, I ordered Young Again Zero Mature after research but vet disagrees with my choices. Any advice would be helpful!!!
