How do pets navigate? This talk is about how pets can find a way home over long distances. Many people hear stories about pets traveling many kilometers to home. Couple of years a lost cat called Holly traveled 200 miles to get home. Scientists can explain how do pets do that. There are 3 main ways. Cats and dogs have powerful sense of smell. Smells like a sight posts, they let you know where you are. Visual landmarks also can help. 3rd way is using a magnet force to navigate. Birds also use it to help them navigate over thousands of miles – it tells them where north is. Some scientist think mammals can use it too. Dr. John Bradshaw explain that cats explore their territory in systematic way. They go out in every-increasing circles and construct mental map of a territory. They moving around in bigger and bigger circles until it find a landmark or smell, which can help to understand where it is.
