The cats have become acclimated to the sound of the can opener.
NOT a mechanical can opener. One of the hand-crank ones. And no matter what else is running in the house, no matter what else they’re doing…let either human go into the kitchen and use the can opener, and four cats will teleport there, to curl around and around our legs and meow & chirp (yes, Oreo chirps) & beg & meow & MOMMM!!!!! GIVE US!!! NOWWWW!!!!
well, okay, I was opening a can of tuna for them anyway, but STILL.
