This is so simple, it’s absolutely brilliant! If you don’t want to agree with something you’re not going to read, you can use the fravia method to hack the software to switch the buttons, so you press the ‘disagree’ button. But this takes time and effort.
Alternatively, you could use a bit of cardboard and get your pet to agree of it’s own free will 🙂
