Ah, yes...I had blocked that out of my mind. I must say these 2 are perhaps the smartest cats I've had. I left a plastic container of treats out on the table one time when Dad and Jacqui were going to be coming in (I wasn't home) because Mikey likes to make a break for the free world and they're not allowed out so they need to be distracted anytime someone is around the door...by the time Jacqui came in they had knocked the container onto the floor, wrestled the top off and dumped out and eaten half the treats.
I put the container in the kitchen cupboard and the little buggers jumped up onto the counter, opened the cabinet and repeated the process. I've often said if they ever learn to open cans I'm out of a job...
