Below is a solution to do manual "301 style" redirects in the default .htaccess file.
On the third line (after the line that reads "RewriteEngine On")
Paste:
RewriteRule ^25/ask$ http://www.domain.com/25/what-is-a-cat [R=301,L]
Where 25/ask is the "bad url" and then you have the url you want the viewer to be forwarded to. (The Redirect 301 method doesn't work because adding [L] after that line is improper syntax.)
I hope this is helpful to others. If there's a better way to accomplish the above, please comment. Thanks!
