Is this a possibility?

Some animals like dogs/cats can detect another life being NOT by smelling it but it is something other which is detectable from at least 5-10 meters. Like simply the presence of another live body somehow transmits energy which dogs/cats can detect. So why shouldn't it be possible for human beings? I have a cat which manages to sense a man around 10 meters away from her. There is no time for the smell to be travelling that fast.
