Maybe have chews. . . bones to keep them busy. How about just putting a piece of paper that you know won't hurt them, and leave it for them to tear up. Sounds as though they are just bored, and trying to find things to do. Also chew and bones you only let them have when you leave, so there's that they're a novelty.
Best way is just to direct what they are doing to stuff that's 'allowable' rather than finding stuff to play with on their own.
Good luck. |
