Okay, this cat is crazy smart. I keep his teaser toys in a table drawer in the bedroom. One morning I woke up to find feather toys all over the bed. I could not understand what had happened at first. Then I saw the drawer was open. He knew that is where I kept the toys and he had been studying it for a while. He finally figured out how to open it. He had been pulling out his toys and was bringing them on to the bed one at a time.
It became a routine for him. If I was not paying attention to him, he opened the drawer and came running to me with a feather in his mouth and drop it at my feet. (Think dog here.) So I had to figure out a way to lock a drawer that did not have a lock. I shimmed it (Marshaguyver style). It has stopped him for now. But he is studying the bottom of the drawer to see if there is a way to get it out. I give him a month.
