My Zoe perches on the back of my chair when I am online. She peers over my shoulder, I could swear she is trying read what I am typing.
I suspect they are draw to the click of the keys...
One I care-give is can get obsessed with a laser pointer. Sometimes she will shut off the computer as she may relate to the red light on it in the same manner.
She is a darling, more of a "Dat", (some puppy antics). I hold her under her front arms pits~ and rock her side to side allowing her bottom half to gently swing, then she calms down to allow me to type for A WHILE... between laser shows! .
She also jumps IN the tub and up the tile wall after the red light pointer, (available at dollar stores now IN the feline toy section), as if playing basketball. SHE KNOWS the source of the light via the clicking plus that she can NEVER catch it, but it is all in the process of having the FUN of the chase! ahahahaha.
They are as human 'kids', very unique...
