I bought this feeder about six months ago because I was going on a trip and didn't want my pet sitter to worry about feeding my cat on schedule. Sadly, this was the only automatic feeder my pet supply store sold. It worked well for a few weeks and then began dispensing food erratically, at odd intervals, or sometimes not at all.  I changed the batteries several times but it didn't help.  It has stopped working altogether.  Don't waste your money.
