Here are a few options for the WordPress post_tag description, keeping in mind succinctness and relevance:

**Option 1 (Concise & Keyword-Focused):**

貓咪白血病治療方法、藥物、護理。 (Māo mī bái xiě bìng zhì liáo fāng fǎ, yào wù, hù lǐ. – Cat leukemia treatment methods, medications, care.)

**Option 2 (Slightly More Informative):**

了解貓咪白血病治療選擇、治療過程與術後護理。 (Liǎo jiě māo mī bái xiě bìng zhì liáo xuǎn zé, zhì liáo guò chéng yǔ shù hòu hù lǐ. – Learn about cat leukemia treatment options, treatment process, and post-operative care.)

**Option 3 (Focus on Shared Experience):**

分享貓咪白血病治療經驗、心得與資源。 (Fēn xiǎng māo mī bái xiě bìng zhì liáo jīng yàn, xīn dé yǔ zī yuán. – Share cat leukemia treatment experiences, insights, and resources.)

**Option 4 (More Comprehensive):**

貓咪白血病治療與護理，包含診斷、藥物、支持性療法及日常照護。 (Māo mī bái xiě bìng zhì liáo yǔ hù lǐ, bāo hán zhěn duàn, yào wù, zhī chí xìng liáo fǎ jí rì cháng zhào hù. – Cat leukemia treatment and care, including diagnosis, medication, supportive therapy, and daily care.)

**Which option is best depends on the overall tone of your blog. Consider these points when choosing:**

* **Keyword Relevance:** Make sure the description uses relevant keywords like “治療 (zhì liáo – treatment),” “白血病 (bái xiě bìng – leukemia),” and “貓咪 (māo mī – cat).”
* **Clarity and Conciseness:** Keep the description short, easy to understand, and to the point.
* **Audience Understanding:** Consider what your readers are looking for when they browse tags. Do they want general information, support, or specific treatment details?
* **Blog Style:** Match the tone of the description to the overall style of your blog.
* **Character Limit:** While WordPress doesn’t always strictly enforce it for the tag description, keep in mind short descriptions generally work better.

No matter which description you choose, remember to update the tag description when you post new content to keep it up to date and relevant. I also recommend using Traditional Chinese characters to ensure readability for your target audience.
