Our cats are bullying the neighbor's dog

Notice our cute little kitten sitting in the flowers, and see the dog through the slats of the fence? Yes its a little hard to see, but the dog was moving around a lot so it was hard to get a good shot. The cat is actually taunting the dog. She even stands up and bats the dog on the nose with her little paws.

We think both cats enjoy teasing this poor dog. As soon as they hear him bark in his backyard, they will run to the fence if they are outside or meow to him through the sliding door in the living room. The dog, of course, goes nuts barking and his people make him go inside.
