My cat, Puss, always comes running when she hears the bag! She knows the difference between the sound of a chip bag and her snack bag, that's for sure! Puss only loves temptations treats. She won't eat other brands of treats. She is a very picky cat. She loves the turkey flavour, chicken flavour, and beef flavour. She isn't very fond of the salmon or anything fish related. But she definitely gobbles up a bunch of treats when we give them to her. She sometimes even tries to sneak some out of the bag when we aren't looking, and 'forgot' to zip up the bag.
