Cats can eat shrimp regularly, as shrimp is very beneficial to their health, containing abundant minerals. However, it's important to pay attention to how the shrimp is prepared. Raw shrimp can easily contain parasites, which can pose a significant threat to a cat's health. Shrimp must be cooked thoroughly before feeding it to cats to avoid digestive issues or viral infections that could lead to illness. 
Benefits of cats eating shrimp:
1. Supplement nutrition. Shrimp is rich in protein, calcium, phosphorus, iron and other minerals, making it an excellent nutritional supplement.
