I was thinking of purchasing one while keeping a couple of regular boxes for them to use, just to see who is willing to use it and who is afraid of it. (catfooddispensersreviews.com)
This would include younger kittens (get them trained on regular boxes first, then introduce this when they get a bit older and have the hang of things). (cat-lovers-only.com)
There are three different subscription options: the 1 - pound Small box is $ 14.99 for 5 - 7 snacks and candies, the 1.5 pound Regular box is $ 24.99 for 8 - 12 snacks and candies (1 DIY kit), and the box reviewed here, the massive 2.5 pound Premium is $ 34.99 for 13 - 17 snacks and candies (1 DIY kit, 1 drink and 1 special item).
