You did the absolute best thing for dear Casey ..... you ended his suffering, in a loving, and respectable way. I honestly believe that prolonging life through testing, medications, treatments, etc... is often just prolonging the pain and suffering, and postponing the inevitable! You were a loving mother to Casey for many years, and I do know how deeply you are hurting. I lost my "kitty boy" Mittens on Labor Day 1999, and it still hurts to this day.

Try to find comfort in knowing that Casey is no longer suffering!
