My kitties ignore my voice, but they come running if they hear crunchies being poured into the food dish. And one of them comes running if we get cheese from the refrigerator; she knows what the packaging sounds like.
my dogs know that sound.
String cheese, brick cheese, sliced cheese, grated cheese.....
here they come.
Our four LOVE turkey from the deli, and will come running from the four corners when they hear the butcher wrap crinkling. Unfortunately for them, the cheese wrapper sounds the same. They hate cheese. If it's turkey, it's a nice day. Cheese? Then it's puke on your pillow or in your shoes.
1 of our cats knows all food prep sounds, but especially the microwave door, and will come running meow talking. So I always say, yes Booboo, I’m making your /whatever and then ignore him lol
