My mom's office had metal blinds with wide slats. The boss' cat - who had free run of the office - liked to stand and bat them. We think she liked the noise. I took a pic of her doing it and enlarged and mounted it as a gift from mom to her boss. He proudly displayed it in his office.
The boss hired his nephew. When nephew saw cat, he said he didn't like cats. Unfortunately for him, this office was where the cat liked to nap and she often walked in on a meeting to sleep on the rug. The cat also like to play with the blinds in his office. We know she did it on purpose to annoy him.
