Sanyuandan ointment is an external ointment for promoting wound healing, removing putrefaction and promoting granulation. Being licked by a cat won't cause serious influence. However, if the cat has vomiting and other symptoms, it may be because oral drugs stimulate the cat's digestive tract, so you can stop taking oral drugs and continue to observe.
The above contents are for reference only. If the cat has abnormal symptoms after licking Sanyuandan ointment, it is recommended to take the cat to the pet hospital in time.
