Cats can eat squid, but it is best to wait until the cat reaches adulthood before feeding squid. Young cats are prone to indigestion after eating squid, and they should not feed too much at a time. Because squid is difficult to digest and contains toxins, if the cat eats too much, it may cause diarrhea, vomiting and other symptoms. Some cats are also allergic to squid, so it is best not to feed it easily. Feed a small amount the first time and confirm Feed the cat after it is no longer allergic.
