Not only could one of my cats hear a packet of crisps opened three rooms away, he could determine what flavour and only come running for cheese and onion, never plain.

Shadow cat will come running when she hears me get the cutting board out or hears the knife hitting the kitchen surface, but only when it's one of the sharp knives, not a table knife. She's associated that sound with the chance of scraps so is always up for a scavenge.

And how is it, cats with a sense of smell 14 times greater than our own, STILL eat tinned cat food when it smells like that?!
