The specific taking time should be determined according to the instructions of the drug or the advice of the veterinarian, because different liver protection tablets may have different taking requirements. If you are not sure, you'd better consult a veterinarian.
In addition, pay attention to the cat's eating habits and appetite. If your cat doesn't want to take medicine before meals, try taking it after meals. But make sure the cat is full, otherwise the medicine may not be fully absorbed.
