Basics: The site consists of categories which will have multiple pages of items offered for download. So once a page reaches a pre-determined limit of items, we'll need to make a new page to add more items. You can see the sorts of pages we'll be making on the site already.
The best example of our menu problem on the test site is the "Pets" menu item. Ultimately, that will show only "Pets/Cats" and the sub-pages in that category won't be in the main menu. They'll be reachable (hopefully) via a menu that sits in the page and looks rather like this:

What we want is for "Cats" to go to the newest page in the category so show the new content off, and then they can drill through the older stuff as desired. So far, the best way I can see to accomplish this is to have the category title in the menu be of the content-type "link" and manually change that link to the newest page every time a newer page is created.
This seems an unnecessary step and I'm wondering if there's some way of doing the menu link so that it's automated instead. Any input is certainly appreciated.
