htaccess 301 Redirect problem

Hi,

I feel like I should know the answer to my question but it seems to be escaping me. Basically I am setting up an htaccess file with numerous redirects to specific pages. In general, this works fine. My problem is when I add a redirect for a top level category, none of the redirects below that work. For instance.

Redirect 301 /category/old-sub-category http://otherwebsite.com/new-page

…works find by itself. But if I do this:

Redirect 301 /category http://otherwebsite.com/
Redirect 301 /category/old-sub-category http://otherwebsite.com/new-page

The second redirect shows up like this:
http://otherwebsite.com/old-sub-category

instead of this:
http://otherwebsite.com/new-page

Any suggestions would be great. Thanks!
