FatBoy passed away yesterday after battling lung cancer for the last few months.The tough call was made to finally put him down and according to Executive Director Kristyn McEwen, it hit them really hard.
 
"As cliche as it does sound, we just thought he would live forever. If love could have saved him, it definitely would have. We're having a hard time processing it today."
 
FatBoy climbed to fame after the shelter put him on a diet to help the giant kitty lose weight as, at one point, he was too big for the kennels. He then became part of the Humane Society family and the mascot for the shelter at local events generating thousands of dollars in donations to the shelter.
