What is FeedCatch? It is a free service by FeedShake for archiving headlines in an RSS feed.

Usually, RSS feeds give you a limited number of latest news, articles , links etc... When a new item is listed the oldest one is deleted from that feed. This is not a problem unless the webpage is updated too often. To make it easier to follow your feeds, you can use this service. Every item will stay in this feed forever or until you follow its link and/or it gets too old.
