The Sponge Bob I refer to is the cat. Not just any cat though, this Sponge Bob was a 33 pound kitty whom The Daily Mail says was a bit of a star in New York, New York.
His weight did not kill him per se; his weight made an operation life threatening so his owners decided to see what would happen. His death is what happened.
Went through the same thing with Grandma Shields we did.
