Why does she do this?

She's a cat. She doesn't need a reason.

that's interesting, but what do you think of this?

Cats don't like having a finger pointed at them; they take it as a challenge.

She’s clearly training for the Olympic dramatic sigh event. Gold medal material.

Learn to speak cat and do what she says or … CHOMP!

Nooooooo She should learn how to deal with cats.

Because she can! lol

She rules the house obviously

You are sitting in her chair 😛

Because you're calling him a she.

Boredom. Play daily with your cats (obviously not with your hands).
