**Key Things to Consider When Choosing:**

* **Your audience:** Who are you writing for? Are they beginners or experienced cat owners?
* **Your site’s content:** What kind of articles do you typically write? (e.g., mostly prevention, or a mix)
* **Post Focus:** Consider the typical topic of posts you assign this tag to.
* **SEO:** Keywords like “貓皰疹病毒,” “FHV-1,” “貓咪,” “症狀,” “治療,” “預防” are important to include, or implied (i.e. “your cat”).

I recommend choosing Option 4 if your site offers diverse information about the topic, or Option 3 if your content focuses on prevention strategies. Option 1 is a good, concise starting point. Remember to choose what’s most relevant to your website and your target audience! Just adapt to your website’s style.
