RSS feed for specific category

I’m trying to do a FeedBurner BuzzBoost, in order to post content from my blog on another site of mine. But I need a way to only show posts for a specific category. For example, when I click on one of the categories in the sidebar, I’m taken to a page with a url of https://domainname/wordpress/?cat=6. But apparently there isn’t an RSS feed setup for that particular page. Which means I can only burn https://domainname/wordpress/?feed=rss2, but then it shows everything.

Is there a way I can create a feed for each category? I really need to break them up. I realize that if the blog was installed under the same domain, I could simply pull in the WordPress variables I need, but that’s not possible in this case.

Thanks for your time.
