Different titles on homepage vs single based on category

Question

For better understanding what I need, I'll give as example the image below.

As you can see, on CAT LOVERS category, I have the full title as "Basic Health & Care Tips to Keep Your Cat Healthy".

Here I need to have a custom title like "Healthy Cat", on all pages (homepage, search results, tag, archive, author archives, etc) BUT keep the full title on single post page (Basic Health & Care Tips to Keep Your Cat Healthy).

There's an example:

I only need this for a specific category, Cat Lovers in this case.

Thank you.

You can use the_title filter hook.

add_filter("the_title", function ($title) {

    if (!is_single() && !is_admin() && has_category("CAT LOVERS")) {
        return "Healthy Cat";
    }
    return $title;
});
