I have two cats, one that barely eats enough, and one that eats until he pukes and puts on weight like crazy. The skinny cat needs frequent small meals, and the fat cat can't have free access to biscuits, so I have been using feeders for them during long work days. My old feeders stopped working, so I ordered two of these.
I was pleased that the feeder was digital and accurate, and both cats got their meals at exactly the same time. It was a bit tricky to set up, but not too bad to get used to. The reason I gave this feeder only one star, is the poor locking mechanism. It took my food loving cat two days to learn how to force the lid open, and as soon as we leave the house he opens the lids and eats both his and his sister's meals. The fat cat was my reason for buying the feeder, and then the feeder is not cat-safe. What a disappointment.
