## 根因

吸入硅藻土（无定形二氧化硅）会导致肺部炎症、肉芽肿形成和类似矽肺的肺损伤，特别是猫和小型犬。

## 解决方案

1. ```
   Use vet-approved topical flea treatments (e.g., fipronil or selamectin) instead of DE; apply between shoulder blades to prevent ingestion.
   ```
2. ```
   For environmental flea control, use diatomaceous earth only in areas inaccessible to pets (e.g., behind appliances) and wear a mask during application.
   ```
3. ```
   If respiratory symptoms develop (coughing, wheezing), provide oxygen therapy (2-5 L/min via mask) and bronchodilators (albuterol 0.02 mg/kg nebulized).
   ```

## 无效尝试

- **Use food-grade diatomaceous earth as safe alternative** — Food-grade DE is still respirable and causes the same lung damage; only particle size differs, not toxicity. (90% 失败率)
- **Apply DE topically on pet's fur** — Topical application leads to inhalation during grooming; pets lick fur and inhale particles, causing both respiratory and gastrointestinal irritation. (85% 失败率)
- **Mix DE with water to make paste** — Wet DE loses its abrasive properties and becomes ineffective against fleas; once dry, it again becomes respirable. (95% 失败率)
