The skinny, onyx-black cat showed up on my parents’ front porch out of nowhere, basically just materializing one day. He was a scaled-down, spitting image of their cat Jinx, who he imitated and followed everywhere, quickly earning the moniker “Shadow.” Since then we have gotten married, moved five times, lived in three states, welcomed two beautiful daughters, said goodbye to old friends, made some wonderful new ones and much more. Shadow has been part of our family through it all, a calming influence who could always lighten the mood with his unconditional affection and playful antics. Then two months ago we could tell something wasn’t right. He was not eating, had lost almost a third of his body weight and basically just wanted to sleep in the closet. Sure signs that a cat doesn’t feel well.
