My previous cat had that problem. She went through two computer mice (no jokes, please), one keyboard, the power supply for the network switch twice, two cell phone chargers, three sets of Christmas lights (off the tree), several network cables, and I've lost track of what else.

I had no choice but to lock her away from the computers, hide the cables well so she couldn't reach them, and wait for her to grow out of the phase. (Several years!)

EDIT: The bitter spray and sour apple sprays did NOT work. My cat seemed to like the taste.
