Pros: Doesn't get knocked over, holds a large amount of food, easy to clean.
Cons: Let's a lot of food out making over eating and eating to fast a thing, can be hard to pour the food in for bigger bags.
We have had this feeder for about 6 years now, it is nice to have something that holds a lot of food seeing as we have 5 cats (was 7 when we got this). With that many doing feeding times in the day would be hard. If this feeder works for you it really depends on your cats, if you have over eaters or ones that try to guard the bowl this one might not work for you. As far as filling it and leaving it out the food last about 2 weeks. A couple of my kitties do try to over eat when I first fill it, so I just watch over them and talk to make them eat slower. (They look at me when I speak to them)
