Options +FollowSymLinks 
RewriteEngine On  
RewriteBase /path/to/your/directory 
RewriteRule ^(.*)cat/(.*)$ cat\.php?slag=$2&%{QUERY_STRING} [L]

put the above in your .htaccess file.. and that would do the magic..

Note : RewriteBase /path/to/your/directory (use this line only if your application is in any of subfolder the folder)

I suggest you obtain a copy of the .htaccess that WordPress uses. It's a quite powerful starting point that allows you to handle routing internally from within your Application - which you might feel more comfortable with, as it seems to me.
