My aunt just won a Kong Dispenser and gave it to me. I had never heard of such a thing but its a pretty nifty little device. It dispenses a Kong at 4 hour intervals. If I was able to change anything, it would be to allow me to set the time interval because 4 hours in my case is generally too long, I'd rather have it drop a kong or other interactive toy every hour or 2 hours, but hey its a free toy so can't complain! It must be new on the market because when I search it its hard to find. Amazon has none in stock and they run about $140-$150 for it. I think the price will go down once more are made. Here is a video of how it works.
