WP does that by default.

(if the Codex works…)
Edit. Oops, wrong link. But still, the first sentence is valid.
The wp_list_cats template tag for sure has a parameter that will display the RSS feed for the category.
Template_Tags/wp_list_cats – see the parameters!
Think I may have missed something. I would like to have a RSS feed off each category in the event that people only want to receive podcasts from the one category instead of the whole site. I went to this page http://codex.ww.wp.xz.cn/Template_Tags/wp_list_cats and looked up the following:
Display Categories With RSS Feed Links
Displays Category links sorted by name, without showing the number of posts per Category, and displays links to the RSS feed for each Category.
<?php wp_list_cats(‘sort_column=name&optioncount=0&feed=RSS’); ?>
I inserted this into the sidebar template and it now displays a list of the categories (without the number of posts) but with a RSS link unique to the category e.g.
http://websitedomain/podcasts?feed=rss2&cat=4 and
http://websitedomain/podcasts?feed=rss2&cat=3
However, when I subscribe to any of the category feed I get all posts from all categories, not just the category I selected.
Did I have to update other files for this to work?? Any ideas appreciated! Cheers!
