Cats can eat a moderate amount of pork liver. Pork liver is rich in protein, fat, iron, and other nutrients, which can provide cats with ample nutrition, prevent anemia, and promote their development. However, cats should not be fed too much at once, as excessive intake can easily lead to indigestion and may even cause vitamin A poisoning, resulting in kidney failure. Therefore, owners should be careful not to feed their cats too much pork liver. 
Precautions for feeding cats pork liver:
1. Pig liver must be cooked thoroughly before feeding it to your cat, and no seasonings should be added.
2. Owners can mix cooked pork liver into cat food for their cats to eat, or add other nutritious foods to the pork liver for them to eat together.
3. If your cat vomits or has diarrhea after eating pork liver, take it to a veterinary hospital for treatment immediately.
