The buttons on my automated floor droid make it easy for anyone to use, even a small cat.Twice now I've come home to find the thing roaming around with Chiclet stalking as best she can. It sucks up the smaller cat toys, which I'm sure she didn't intend to happen, so I have to pry them loose from the innards.
Still, it would be nice if I could somehow train the little beast into turning it on when she kicks kitty litter all over the floor, but we are still working on "don't jump into the fridge while I've got my back turned or else I will shut you in there".
