Yunnan Baiyao is not recommended for cats. Although Yunnan Baiyao has the effects of promoting blood circulation, removing blood stasis, reducing swelling and relieving pain, it is used by people, and some components in the medicine may have adverse effects on cats. If the cat has a muscle strain, the following measures are recommended:

1. Rest: Let the cat rest in a quiet and comfortable environment, and avoid strenuous exercise and touching the affected area, so as not to aggravate the injury.

2. Observation: Pay attention to the cat's injury, such as swelling, pain, fever and other symptoms, and seek medical attention in time if it is abnormal.

3. Hot compress: You can apply hot compress on the affected area to help relieve pain and swelling.

4. Appropriate medication: you can apply an appropriate amount of anti-inflammatory ointment or oral anti-inflammatory drugs to relieve inflammation and pain.

In short, when dealing with cat muscle strain, don't use Yunnan Baiyao at will, but follow the veterinarian's advice. If the injury is serious, please seek medical attention in time.
