Cats can eat crawfish, but it’s not recommended as their regular food. Some cats may be allergic to shellfish, so give small portions and monitor for reactions. Cook crawfish well and remove shells and bones to prevent choking. Don’t add spices or seasonings as they may be harmful to cats. Crawfish can be given as an occasional treat, but it shouldn’t replace a balanced cat food diet. Consult a vet before introducing any new treats to your cat’s diet to make sure it’s safe and appropriate.
