So cute!
You are so lucky if you have just one item that sets them off. lol My cats come running if they hear any type of ceramic/glass dish hit the counter, any type of silverware hit a glass or ceramic dish, any can being opened, when the microwave beeps, any bag that resembles the temptation bags (sound, size or looks), smell any meat or when any of the dog or cat food containers or treat jars are moved, opened or bumped into.
