Cats can eat boiled shrimp, but the following points should be noted:
1. Ensure the shrimp is fully cooked to avoid parasite or bacterial infection.
2. Remove the shrimp vein and shell before feeding to prevent the cat from having difficulty swallowing or choking.
3. Do not add any seasonings, such as salt or oil, as these may be harmful to cats.

4. Shrimp should not be a major part of a cat's diet to avoid nutritional imbalance.
5. Some cats may be allergic to shrimp, so you should carefully observe their reaction when feeding them shrimp for the first time.
