Cat: "Finally broke free of my captors and explored the outdoors. Gave hooman a heart attack. 10/10 would do again."

I have a very similar (but much chunkier) tabby cat and I honestly worry sometimes that if he escaped I would have a hard time identifying him if he lost weight or was injured. He looks almost identical to your cat. Glad your little buddy returned!
