How efficient are these to deter diggers and door scratchers?  I've tried
everything to keep mine from constantly digging at the carpet in front of
the door, and tearing up the door.  Mine are usually out most of the
night and part of the day, then back in the cage for a break, and so
on..but all they do after a couple of hours is work at that door.
 
I don't know if they're bored (and if they are, how I could spice up the
area anymore than it already is..  They have loads of toys/tunnels/etc..)
or what..but it's too aggravating.
 
So yeah, scat mats, how well do they work and are they safe?
