Ah, I see what you are talking about now (what I initially thought but you weren't specific enough at the beginning). You want to protect the Categories feature on these pages, not the categories themselves. Protecting the feature changes how it works and wouldn't likely be allowed through Wikia's Customization policy. I see though that the page has no protection. Are these categories usually added by IPs and new users? If so, you'd have better luck protecting the entire page from these users ("Block new and unregistered users"). Still, clear policy can also help prevent the addition of unwanted categories.
