When working from home, many people’s cats will likely interrupt Zoom calls and walk all over the keyboard. To keep a cat away from a computer, you could fight a losing battle to push the cat away, or you can tempt the cat to find something else to attack.
That seems to be the solution for a cardboard box divided into parts where you can hide a treat. Now the cat has to figure out how to find and get the treat so you can work in peace for a while. Since the puzzle toy is made out of cardboard and cats seem to love cardboard, it’s an extra incentive for the cat to play with it.
