My husband's reply... "I didn't know I was supposed to lock them in. All you told me to do was bring the litter box up."

LOL Why would I have you move the litter box from its regular location to a new one if I didn't want them locked in? Every other time I've had him move the box, it's to shut them in the spare room/bathroom.

No harm was done, though it was hard for me to listen to them meowing and scratching the door to get out of that room for the last couple hours. But they're out now, and fed, and happy so all's well that ends well! Back to my movie...
