Why is There no Cat in the Chinese Zodiac?

An ancient folk story called the "Great Race" tells that the Jade Emperor decreed that the years on the calendar would be named for each animal in the order they reached him. To get there, the animals would have to cross a river .

The Cat and the Rat were not good at swimming, but they were both quite intelligent. They decided that the best and fastest way to cross the river was to hop on the back of the Ox. The Ox, being kindhearted and naive, agreed to carry them both across. As the Ox was about to reach the other side of the river, the Rat pushed the Cat into the water, and then jumped off the Ox and rushed to the Jade Emperor. It was named as the first animal of the zodiac calendar. The Ox had to settle in second place.

The third one was the Tiger. Even though it was strong and powerful, it explained to the Jade Emperor that the currents were pushing him downstream.

Suddenly, from a distance came a thumping sound, and the Rabbit arrived. It explained how it crossed the river: by jumping from one stone to another, in a nimble fashion. Halfway through, it almost lost the race, but it was lucky enough to grab hold of a floating log that later washed him to shore. For that, it became the fourth animal in the zodiac cycle.

In fifth place, was the flying Loong. The Jade Emperor was wondering why such a swift airborne creature such as the Loong did not come in first. The Loong explained that it had to stop by a village and brought rain for all the people, and therefore it was held back. Then, on its way to the finish, it saw the helpless Rabbit clinging onto a log, so it did a good deed and gave a puff of breath to the poor creature so that it could land on the shore. The Jade Emperor was astonished by the Loong's good nature, and it was named as the fifth animal.

As soon as it had done so, a galloping sound was heard, and the Horse appeared. Hidden on the Horse's hoof was the Snake, whose sudden appearance gave it a fright, thus making it fall back and giving the Snake the sixth spot while the Horse placed seventh.

After a while, the Goat, Monkey, and Rooster came to the heavenly gate. With combined efforts, they managed to arrive to the other side. The Rooster found a raft, and the Monkey and the Goat tugged and pulled, trying to get all the weeds out of the way. The Jade Emperor was pleased with their teamwork and decided to name the Goat as the eighth animal followed by the Monkey and then the Rooster.

The eleventh animal placed in the zodiac cycle was the Dog. Although it should have been the best swimmer and runner, it spent its time to play in the water. Though his explanation for being late was because it needed a good bath after a long spell. For that, it almost did not make it to the finish line.

Right when the Emperor was going to end the race, an "oink" sound was heard: it was the Pig. The Pig felt hungry in the middle of the race, so it stopped, ate something, and then fell asleep. After it awoke, it finished the race in twelfth place and became the last animal to arrive.

The cat eventually drowned and failed to be in the zodiac. It is said that this is the reason cats always hunt rats and also hate water as well.
