Thanks, Lori. I'm starting the pred tomorrow and I hope that he'll cooperate while I try to give him his pill. He hates the new food so I'm just going to continue feeding him the Natural Balance Venison & Green Pea and see how it goes. Luckily the Purina EN was just a little under $3.00 because it's sold in packets of eight so I didn't waste a lot of money this time. I'll continue to keep you updated.
