The sound we make is more like heavy breathing or sniffing, as if we are blowing the nose without hand holding the nose.
The cats would seem a little nervous (not sure), they would stand up if they were lied down, sometimes sniff back, they would meow, wondering around the person, or run away. One of my cat lies on his belly and meows.
What does all these mean? We are very curious what the cats are thinking. Do they believe we no longer recognize them if we "sniff" them? I tried to "sniff" my neighbor's cat who is always friendly, he ran away when I did that...
Anyone have a clue or similar experience?
