Has anyone tried these treat dispenser / camera / speaker thingies? Husband saw the Furbo on Amazon today (I afflicted him with my addiction, muwahaha!) and we're going to give it a whirl. I'm sure Gertie will catch on, but Abbi leaves me dubious. Momo would exploit the thing to his whims. With a 30-day return policy we can't lose so we figured, "why the heck not?"
