## 根因

除虫菊酯对猫有神经毒性，因其缺乏葡萄糖醛酸化代谢能力；即使标签注明'对猫安全'的产品，在敏感猫或高剂量下也可能导致震颤、癫痫和死亡。

## 解决方案

1. ```
   Replace with isoxazoline flea treatments (e.g., fluralaner, sarolaner) specifically approved for cats, following weight-based dosing
   ```
2. ```
   Use fipronil-based spot-on (e.g., Frontline) for cats, which has a wider safety margin; apply to base of skull and monitor for 24 hours
   ```
3. ```
   If pyrethrin exposure occurs, immediately bathe cat with mild dish soap and water (no scrubbing), then contact veterinary emergency; do not induce vomiting
   ```

## 无效尝试

- **** — Natural pyrethrins are still neurotoxic to cats; concentration and metabolism are the same (85% 失败率)
- **** — Cats are extremely sensitive; even sub-label doses can cause toxicity, and underdosing fails to kill fleas (90% 失败率)
- **** — Cats groom themselves, ingesting the product; neurotoxicity occurs via dermal and oral routes (70% 失败率)
