Weruva Polynesian BBQ Wet Cat Food Can features Red Bigeye as its distinctive ingredient, layered over sardine cutlets and whole meat tuna. This recipe reflects the natural diet of carnivorous, nocturnal cats, with "bigeye" named for the fish’s notably large eyes. Native to tropical and subtropical waters of the Pacific and Indian Oceans, Bigeyes are often found near rocky outcrops or reefs.
