Kitten copies his rabbit companion and hops
This is a classic case of a kitten learning by observation. It just so happens that his owner has a pet rabbit as well inside the home and therefore we see the kitten hopping in following their rabbit companion. That's my take on what I see in this video. It is charming and it is cute. I don't think that it will become a habit that lasts throughout the adult life of this kitten. It's just a temporary state of affairs because of the kitten's observation of what he or she sees at that moment.

It's a reflection of how kittens learn from their mother. They learn to eat prey animals and then to hunt prey animals from their mother. It's their journey to becoming independent at which point they leave their natal range and find their own home range if they are living in the wild and not in someone's home. I am referring to true wild cats and the ancestor of the domestic cat.
You have probably seen domestic cats opening fridge doors, opening doors, even opening windows and other human activities which they've picked up through observation of their human caregiver. I've even seen a young cat watching boxing on television. The kitten started to box while sitting on his hind legs. It was an exact copy of what they saw on telly! Cats can copy complex human movements.
