After fifteen years, I am so happy that we made that decision; he has been an awesome cat. In September of 2017 he developed kidney cancer and when he stopped announcing himself, we knew that it was time to let him go home. It is so hard to say goodbye to a dear friend and kitty kid. I know he is with his past fur friends and happy. He will be truly missed. We love you Turbo Booster Boo, Rest in Peace until we meet again.
