Any time you try to use a computer, you can be sure a cat will try to lay across your keyboard or just stand in front of the monitor so you can’t see what you’re doing. While you may think your cat is trying to drive you crazy (a valid assumption), there’s actually another reason why cats behave this way.
Cats see their owners using a device that’s occupying their attention so the cat naturally wants to be near that center of attention. That’s why cats like computers so much. If you sat in front of the washing machine for hours at a time, your at would probably like the washing machine just as well.
