Explain me this... How do dogs and cats know their "masters" or other family is coming way before they get there? My dog which passed away some years back would get up and come to the door at least 5-10 min before someone from our family or relatives that would often visit even get there? Same with my cat today. He is at the window exactly a few minutes before someone arrives and my wife tells me he does the same when I am coming home.
