Oh Karen, I'm so sorry to hear that...........I have tears in my eyes, and my heart breaks for you. I've never lost a pet before, but I can only imagine how it must feel. I know this must be really hard on you, with his toys and food bowl and all, but you'll always have good memories of him.
Since he was in great pain, you did the right thing. I know it will be hard on me watching one of mine suffering, and I can't do anything about it. But now, your Cody is no longer in pain, and is now at the Rainbow Bridge.
