The Fishing Cat is one of the most unusual wild cat species in the world. It swims, dives, and hunts underwater, and is often cited as proof that cats are natural fish eaters.

Separated by millions of years of evolution, their biology has not changed, only their opportunity. This deep dive into feline evolution challenges modern feeding myths and explains why fish was never meant to replace meat as the foundation of a cat’s diet.
