I can not hold back my tears! Hua Hua was an angel!

My April was passed away by heart failure. She knew that she was going to pass. She was kept peeing and pooping to clean up herself after breakfast. Than she was lying down on my way behind the front door, first time did not want me to leave. She did not have any symptoms , and even any sufferings. So I was not understanding her meaning! I was not aware the all! Until the night I came back home, she was not waiting for me by the door first time, I only found her cold body was lying down against the kitchen wall below the window with her left eye still opening. She was apparently waiting for mom to be home to say "Goodbye! " to mom!
