You have to have a "sender" and a "receiver" for critter-human communication. Some of us are lucky to have and appreciate the gift.  Our dear departed kitty, Edna, who passed recently at 19 years old,  could get a hundred different meanings out of "muh-row?" Luckily, I was a fast learner and could always read them.  When Edna was in her final illness, we had to apply a thyroid medicine to the inner leather of her ears.  She would ask me for this multiple times a day, past the normal dosage.  She just loved the extra attention. I don't go so far as to say she knew that the meds helped.  Anyway, I would get a closed chapstick and "apply" that to her ears.  This made her happy and she would then be contented and happy.  I hope somebody reads me that well when I am old and sick.
