That seems to imply that you pick up your cat and have him press the button so you can say "it wasnt me!"... whereas in your case, you did not coerce the cat to press the button for you, so was it truly your instrument, or random occurence.
I feel like you would be responsible for any key presses on your laptop, regardless if made by the cat or not. Maybe someone can give an expert opinion.
I don't think that's entirely true. If an acquaintance used your laptop in front of you to hack into a bank, you might be responsible.
But if Microsoft automatically downloaded BankHacker 3.11 to your machine and set it to pop up a dialogue box so that hacking into a bank was so simple your cat could do it — and if then your cat "used your laptop to hack into a bank", then common sense says that Microsoft would be responsible.
