Cats generally do not eat or drink for eight hours before sterilization. The reason why cats need to be fasted and water-free is to prevent cats from experiencing reflux during anesthesia. Cats also need to fast for eight hours after surgery. Of course, we just need to follow the doctor's advice on how long we should fast and drink.
Tip:
If a cat is not neutered, it will go into estrus frequently, and prolonged estrus will increase the cat’s risk of contracting diseases.
