Well my little punky butt does that, but only one cupboard. He doesn't seem too realize all the cupboards open the same way! He only does it when I turn my music up loud. Does your kitty do it in various places of home when he wants peace and quiet? I'm no expert, just throwing out a question? Do you have an active house? Or maybe live where mice be invisible to you, but not to him? I live in a house and both my cats have brought me their trophies. Just throwing out suggestions
