My kitties all respond, but differently..
MowMow used to trill an run to me, but now he's lazy so he just returns them. Book doesn't return them, but flops on his side and thrills for belly rubs. Neelix just looks at me like I'm wacko.
What still gets MowMow moving is if I nod my head up (short quick head jerk up), smack my lips, and then wink at him. I do that a few times and his eyes dilate, a few more times and he comes running to play.
Then Neelix pounces him and he gets mad and the fun is over......
