{{Messy cat}} is a template that allows you to flag a category that needs some improvement. Users should simply type {{Messy cat}} at the top of a category page, publish that edit, and then proceed to that category's talk page to explain what needs to be changed.

This template will automatically gather up all pages that use it into a single category that will be easy for admin to find and use.

This category needs some help.

The basic structure of this category is obviously messy. Any one of the following might be true:

It's got more than 100 individual pages in it, which means that subcategories are clearly indicated.
Its subcategories aren't symmetrical — they seem to be about things of unequal weight. Maybe there are super-general subcategories co-existing alongside very specific ones.
The category name itself is unfocussed, allowing for multiple interpretations of what kind of information should be included.

Please make sure that you leave a note at Category talk:Messy cat which explains why you think this category is messy.
