It is not unusual to see dogs chasing cats. It is in their nature to “remove” other predators from their territory. However, when they are very young puppies don’t rely on this particular instinct and they can even become friends with kittens. In order to prove that, the creators of this video have placed few kittens and few puppies in the same room and filmed them.
Their reactions were very interesting. At first, they were all cautious, but once they have realized that they have animals that are similar to them they all started playing and fooling around in the room.
