My husband's magic

My hubby uncovered a secret talent the other morning. As he and oldest son headed out the door, hubby looked Zac in the eye and commanded, "Purr!" Much to their amazement, Zac complied immediately. Granted, it doesn't take much to make Zac purr (he's such a happy kitty) but we never thought he'd do so on demand. Hubby has given a repeat performance with the same happy rumbling response from Zac. The rest of us have tried and failed to perform this astonishing feat.

I'm not sure whether to be more astonished at hubby's ability or at Zac's malleability.
