I have a Pet Mate C10 (ha! the one a Bengal beats in the video linked above!) which works well for a one-off timed serving of food. We use it on the daily to give the cat breakfast because the early-morning miaowing was getting very annoying until we worked that out. It is covered in scratches from when she tried to defeat it, but otherwise going well just over a year in. Looks like the Cat Mate C100 is about the same thing with nicely rounded corners.
For a whole weekend we get someone to pop in once a day and top it all up along with her regular dish so that the cat gets her two servings, then the timer’s good to separate them. Our cat is a greedy ****.
If you’re only doing dry food there are dispensers on Amazon and the like that seem as if they’d handle longer periods of time for you. Basically a big bucket with a timed opening into a dish below, for about £60, or a little bit more for wifi access haha.
