IMy cats can open cabinets as well. They always get in the bathroom cabinet and the linen closet. Once, one of my cats turned on the OVEN!

That knob doesn't have to be pushed in to turn it on. He must have rubbed against the knob.
I came home to find my oven on BROIL and boy was it hot! Now, I have the know duct taped to make sure it doesn't happen again.
