I would be concerned about the price too, although I didn't take a peek at it, especially if my 40 lb princess were to step on it...but as for the interaction...well, sometimes the main interaction we get is a screaming battle to the death for control of the mouse (or shovel, or toothbrush, or whatever). I know dd 'can't' do things as quickly as me, but I tell you what, she REALLY wants to try. So at first it takes longer, but then she gets it, like with brushing (I still check and get yelled at, but I have to check!).
Anyway, if your Mr. W is exhibiting a similar..ahem, "need for freedom", I can definitely relate to wanting to offer that! smile
