When our pets have a new experience, their reactions can be awesome. The title for the cat picture above is "We forgot to tell our cat that we had a baby." Yeah, she is surprised, to say the least. In the sequence below, the guy bought and used a vacuum cleaner of the first time. You have to wonder how much cat hair he had to clean up by then.
It's not just cats. Dogs can surprise us with their reactions, too, like this dog who had never seen kittens before, but then suddenly was confronted by four of the infernal fluff balls.
