I'm not clear on what you're trying to do, though, when you say [you] "are using Pages to distinquish their different categories".
If you want to organize or style your site differently, or display different static content when a particular category is displayed, you might try nixing the Page idea and implement the following.
CASE 1: You want some text displayed before all the posts when a user follows any any Category link (i.e. the same text for all categories).
Create in your theme directory a file called
category.php. Actually, you might want to copy
page.php over to this new
category.php so you don't have to write as much code, just alter it instead.
At any rate, this is the template that WordPress will reference whenever a Category link is followed (see next post for a detailed description on what templates WordPress tries to use in this situation). Above The Loop, put in
<div id="sticky-snip">This is some text that will always display when any Category link is followed</div>
CASE 2: You want different text to display above the list of Posts from the Category depending on what Category the viewer is looking at. Example: Display "These posts are all about cheese" for the "Cheese" category, and "I am not wearing any pants" for the "Shorts" Category, and "The following is a list of posts about some particular topic" for ALL OTHER CATEGORIES.
Rather than making a template with lots of
if statements, WordPress allows you to do the following nifty trick.
category.php as above. Put
<div id="sticky-snip">The following is a list of posts about some particular topic</div>
above The Loop.
Figure out the Category ID of the Cheese Category. Say it's 6. Create
category-6.php as above. Put in
<div id="sticky-snip">These posts are all about cheese</div>
above the Loop.
Figure out the Category ID of the Shorts Category. Say it's 19. Create
category-19.php as above. Put in
<div id="sticky-snip">I am not wearing any pants</div>
above the Loop.
See http://codex.wordpress.org/Theme_Development for more details about WordPress Templates.
In either of these cases, you just need to list the Category links with wp_list_cats. No Pages are needed. WordPress uses these new templates automatically.
EDIT: As I said, I don't quite know what you are trying to do, so perhaps this does not address your issue at all.
