Where Did You Go, Mr. Black?

Have you ever wondered where your cat goes when they are outside? Do they go to the neighbor's house and ask for food? Do they spend time with other cats? Do they chase birds? Do they run away from dogs? Where do our cats go and why are they so curious about the outside world? But worst of all, where do they go and what happens to them when they disappear for too long? Do they go on vacation?
