## 根因

猫是专性食肉动物，无法合成牛磺酸；植物性饮食缺乏牛磺酸，数月内会导致扩张型心肌病、视网膜变性和繁殖失败。

## 解决方案

1. ```
   Do not feed any plant-based diet to cats. Stick to high-quality commercial cat food that meets AAFCO standards and is labeled 'complete and balanced' for cats. Example: Purina Pro Plan or Royal Canin.
   ```
2. ```
   If a plant-based diet is unavoidable for ethical reasons, use only AAFCO-approved vegan cat food (e.g., Evolution Diet or Ami Cat) and have blood taurine levels tested every 6 months by a veterinarian
   ```
3. ```
   For cats with allergies to animal proteins, use hydrolyzed protein diets (e.g., Hill's z/d) which are still animal-based but hypoallergenic
   ```

## 无效尝试

- **** — Taurine is heat-sensitive and degrades during cooking; also, plant-based diets lack other essential nutrients (arachidonic acid, vitamin A, niacin) that cats cannot synthesize (80% 失败率)
- **** — Many vegan cat foods are not AAFCO-approved and may still be deficient in taurine or other nutrients; only a few brands meet feline requirements (70% 失败率)
- **** — Occasional meat does not provide consistent taurine levels; the cat's body requires a steady daily intake from animal tissues (60% 失败率)
