On January 25, 1239, Catí was given to populate by Blasco of Alagón to Ramon de Bocona and to forty residents more, this fact was confirmed by king James I of Aragon. The surnames of those neighbors are supposed to come from the land of Lleida. Fidelity was Ramon de Bocona's main virtue which is recognized in his shield weapon whose main figure is walking a dog, a symbol of active loyalty.

Catí has participated in many of the historic events surrounding nearby Morella. Knights from Catí took part in the conquest of Mazalquivir, Oran and Bougie, in the ship belonging to the Bayle of Morella, despite the fact that the town of Catí, along with other neighboring villages, began in 1292 a lawsuit against Morella. The matter was not settled until 1691.
