Bowl hardware has yet to be documented on [Joe]’s project page, aside from the hint that an Arduino (what else?) was involved, but the write up on feline facial recognition is fascinating.

Other than the Arduino the project is cheap (the servo is $13 and everything else you probably have on hand) and shouldn't take much time to put together.

[Domiflichi] likes his cats, but not the drudgery of feeding them. So, like any good engineer, this simple problem became his next project: building an automatic cat feeder. Based on an Arduino ...

Tired of feeding his cat in the usual way, Ben Millam created a primal, yet techie alternative for his cat, Monkey. Millam said the project started when he began to read about why cats repeatedly ...

Jessica , who works as a hardware and software developer, explains on her blog the process of making her own 'cat ear device that moves by reading emotions from brain waves' using Arduino.

In this Arduino project, I show you how to build a simple servo laser tower controlled from a smartphone app called Blynk. This is ideal for making a toy for your cat or dog. #ArduinoProject # ...

Electrical Engineering students, Slaton Bird, Brian Grahmann, and Kelby Lang designed an automatic dog feeder for their project this semester.
