Neko-ryu Goshin Jitsu （Japanese: 猫流護身術）is a martial art created by well known judoka Ernie Cates. Translating as "Cat Style Self Defense," it focuses on simple, natural movements and techniques that can be remembered in times of stress or when under attack. They focus on using the size and power of a larger foe against the attacker.

The concepts preceding Neko-ryu originated with Mr. Nakabiyashi who had developed a four hour self defense class for the Japanese business man. Nakabayashi was later hired by the U.S. Marine Corps to train troops in this art.

Cates was one of three U.S. Marines who studied directly under Nakabiyashi. The Neko-ryu style was fine tuned and is now taught throughout the world. These simple concepts allows the student to utilize the size and power of the opponent against them.

The current title of Sōke (head of family) has been transferred to "Moose" Cates to continue in the development of the style and to continue his father's legacy.
