"She had an enlarged heart (it had to be true because there wasn't a sweeter, more affectionate cat in all the land), blood clots formed and sent her into heart failure. Completely out of the blue," Moore continued. "We're still in shock and processing the pain and grief of this loss but holding her in my arms, making sure she knew she was safe and loved as she took her last breaths will stay with me for the rest of my life."

"This poor cat would suffer through allergy shots every other day and not blink as we tried to get pills down her throat and then hop up in our laps and purr louder than a car engine," she went on to write. "She never held it against us... like she knew we were trying to help her feel better."
