You might be interested in an automatic feeder for your dog or cats for different situations. I will take a closer look at those options later in this post. A good automatic pet feeder though should come with an addition that makes the whole automatic feeding worth while: a voice recorder.
We used to pet-sit two cats and had at their home an automatic feeder helping us that the cats received their food at their usual times. This made it for us sitters easy, we just needed to show up once a day to check if everything was alright, which of course was, those cats were just adorably well-behaved.
