There’s only so much red laser pointer games or ribbon on a stick teasing you can do with your cat.
Sometimes, when I’m really bored, I’ll slip my cell phone under a sleeping cat and then call it with another phone.
Most cats jump up startled, but we had this one cat who would just twitch his ear once and ignore the thing.
It didn’t matter what ringtone was set up, or if I’d set it on vibrate mode. He’d just twitch his ear and ignore it.
We figured he was smart enough to realize the call wasn’t for him.
