  1. Much like dogs, cats use scent as a very important sense. Humans use scent, but not nearly to the degree that cats do. It’s essential in their world. One thing that has amazed me is the degree to which cats can detect if a person was not well. I’ve had a cat sit with me for days, when I was recovering from surgery.


    1. My cats sat on my pillow and watched me when I had the flu. He had a parental look in his eyes, as if to say, “I know you’re getting better, and I’m glad of it.”

      You cat must be very loving, sitting with you for days. Must’ve been such a comfort to you, too.


  2. Interesting. I’ve never noticed a cat sniff another’s behind. Dog’s do it obnoxiously, but I’ve never noticed it in cats. Hmmmm, maybe they aren’t as obvious. It is in any case, dog or cat an identity marker.
