Cats can eat pork liver, but only in moderation. Pork liver can help prevent anemia in cats, boost their immunity, improve night vision, and stimulate appetite. However, pork liver also contains a large amount of vitamin A. If cats consume it over a long period or in excessive amounts, it may lead to vitamin A poisoning, causing pain, lameness, and tooth loss.

In addition, pork liver is high in phosphorus and low in calcium. Long-term consumption may affect a cat's calcium absorption, leading to calcium deficiency and causing problems such as rickets and osteomalacia.
