Can you RSS Feed a WP Category?

Hey guys I’m running 2.02 and I was wondering if it was possible to RSS feed just a category from Blog A to Blog B.

Right now, Blog A has all of my primary entries, and I’ve split it up into Blogs B through D, and I want to keep adding entries to Blog A, and have the entries be fed to Blogs B through D — with B being for one category, C for another, D for another, etc.

Is this even possible? I’ve been reading the Import Content codex, but I can’t figure out what is the rss feed URL for specific categories. Is this even possible?

Thanks.
