Some time ago our kitchen drawer broke (just a little) then the kittens (well Tinker) discovered that he could jump into the broken drawer. This broke the drawer even more and he had a route to either sit in the not quite so broken drawer, or into the kitchen cupboard where he could help himself to packets of people food and things that go 'rustle' (very popular with our cats).
Then his partner in crime (yes, I suspect Casper on this one) has now worked out how to open the bread-bin. Whilst I was out (for fifteen minutes!) this bread massacre took place in the kitchen.
