Ted says: This is a great example of an owner who is playing with their cat using their cat's preferred prey preference (say that 3 times fast). Most cat play is based on their natural hunting and stalking instincts. Most will show a preference for birds (in the air or rodents (on the ground) or sometimes both. If your cat won't play with you, try to figure out what type of prey they prefer and then get toys that mimic them.
Ted says: Yes. He's probably obsessed with the balls, but there's a chance the owner previously reinforced this behaviour (which he does in the clip by talking to the dog and giving him attention). A lot of people think dogs cannot see images on TV but they absolutely can. My dog chases things off the side of the screen and will look behind the TV for them.
Ted says: That pup is very excited! It's typical weirdo puppy behaviour, don't ask me to explain it, but if you watch human two-year-olds they do some pretty unexplainable things as well!
Ted says: This is more fun play behaviour. You can tell the puppy is a bit nervous because I'm sure he's been smacked by the cat before. When he raises his paw it's almost like asking "does anyone want to play?" This is a common behaviour, and puppies love to play tug of war, even with a very passive participant like the cat.
