I recently purchased a medium ERGO auto pet feeder. After some difficulty in understanding how to get the timer working, the directions are poor and the the buttons on the timer are not correctly marked, I got it working.All went well until on the second day of operation. I went downstairs to check on the feeder and the cat. Low and behold the cat had inserted his paw into the feeder spout and was shaking out cat food pellets. He would eat them and then repeat the operation. I then put my finger into the feeder spout and was able to shake the feeding device and get out cat food pellets.Needless to say this was not what I was lead to believe in the product advertising. Failure to make the feeder cat proof is a major design flaw. My cat is no Albert Einstein, so this will be a problem for others.
