Bests & Worsts Reviews from Amazon

I didn't want a unit that could be emptied by a smart cat who noticed that just jarring the side of the unit would dump it's contents over the edge to be eaten...(the pink plastic fingerlike projections one) I didn't want a unit that could fall or be pushed off the countertop and shatter, so no ceramic ones. And whatever it was, it needed a rubber base so it could not be pushed around, it's hard enough for cats to get food out of the things without the feeder sliding away from them while they're wrangling it. Funny maybe, but not fair. Anyhow, this unit is washable, it has a rubber base to keep it on the countertop or steady on the floor, it has a reservoir for the food on top, that can be sealed (lid screws on) to minimize food getting stale, (ceramic and other unit cannot be sealed for freshness), AND it's a clear hopper so you can easily see if your cats still have food. Better still, there are "easy" portals and "harder" portals for cats of varying dexterity. No value in starving an older less agile cat. You don't notice it, and they don't seem to mention it but underneath there's a coarse auger that can be turned to increase or decrease the gap that allows food to drop as the cats harvest it. If this were NOT included in the engineering, cats with small pellet food would get all their food in one drop, and cats with large pellet food would got no drops. So you can turn the auger to widen or narrow the drop-gap and let just the right amount of food through as the cats procure their meals. Here's the skinny: If a fat cat has to solve a Rubik's cube to get something off the buffet, it will wait for a meal til it's hungry. So they lose weight simply by using their own laziness against them! How ironic! Love it.
