In theory yes, but not yet.
Years ago I had a basic idea for a way that I could make my tails move on their own, involving some motors and some stiff cables that ran the length of the tail. But motors and things like that are not things I have any experience with, and life is busy, and I never worked actively on it.
But sometime last year I saw a kickstarter for some people making animatronic tails, and they seemed to be doing it in basically the same way I had figured would work. I was excited. They were offering them with fur coverings like cats and dogs or what have you, but I got one that was just the mechanism and control box so I could at some point build a tail of my own around it.
But life has been busy, and I haven’t gotten around to making it yet. Eventually I will, and once it’s worked out I’ll surely make it available for commissioners.
If people are curious, here’s the website for the people who made the animatronic tails: http://thetail.co/
