Thats creepy. I can say I had similar thing happened with my cat. Totally same fur, with different eyes. Stray can sneak in without being noticed, while pet are attention seeker and noisy. My cat would not eat unless I pat and stoke.

Our mind is more powerful than we think. I don't know peeping into future is possible or not. But few people can actually see the big picture or deduce the whole from only small portion of it. Yes, like jigsaw puzzle you can know how it will end by looking at few pieces but you never know until it happens, it might differ a little.

Life is like Schrodinger's cat. Things happen or things don't happen when you open the box. But what if the box is never opened, cat will die eventually. There is no escape.
