My other cat, Chester, died yesterday.
I raised him since he was just maybe a week or two old, he lived to be about 6 or so.
He was quite the doofus, and semi-feral his whole life, so he never got to understand what it meant to be more of a housecat, and was super shy and stuff. Not sure what he died from, but when I think about it, it was obvious something was wrong for a while, it just kind of got out of control and took him from me within a single day.
