Littlest Pet Shop will return with season four to Discovery Family on November 7, but the network has cancelled the series. This means that season four will be the last.

Roger Eschbacher, a writer for the animated series, announced the cancellation on his website on Saturday. He revealed that Hasbro had decided to pull the plug on the series, and he said it had something to do with toy sales. It was not a case of low ratings.
