Sepideh is a menace, if I have spotify or anything similar going on the tv, she chases the progress bar! I've had to set the screensaver to blank the screen really fast so she doesn't notice it. She's also the one who's mad for the laser pointer, she likes small moving things.
Sune comes running whenever hears lion roars, particularly the one that is at the start of MGM movies. He doesn't react to tiger roars, but did jump up fascinated when he heard leopards doing their cough bark thing on Animal Planet once. But he can't seem to figure out where they're coming from, and hasn't connected the noise with the tv, so he runs around under the furniture looking for them.
I don't think either of them would be much for a cat DVD, well, not unless it had a progress bar for Sepideh.
