Can your pet open doors?

andrew, that reminds me! My Tonkinese can open any cupboard door. The cupboards are always kept closed, but he can open them at will. When I won't let him come into the computer/parrot/exercise room with me, he often throws temper tantrums and slams the kitchen cupboards open & closed. We have one cupboard in another room we keep extra parrot and cat toys in. We have to keep a chair against the cupboard door to keep him from dragging everything out! He's a very naughty boy!
