Why cats and rats are enemies?

Who said cats and rats are enemies? Rat is the one of the tasty items for cats so cat cant consider rat an enemy. Likewise rat thinks he should stay away from all animals who want to eat him but no enmity.

A long, long time ago, the Cat and the Rat were the best of friends. They accompanied each other everywhere they went and they shared their food. One day, the Cat learnt that the Jade Emperor was going to elect twelve animals to represent the twelve calendar years, and invited all animals to a party. The Cat suggested to the Rat that both of them should make a presence.

When the day finally arrived, the Cat told the Rat, 'I am going to take a nap so that I will be in my top form. Can you please wake me up when it's time to go to the party?' 'No problem.' the Rat replied, 'Just relax and rest. I will wake you up when the time comes.'

After the Cat fell asleep, the Rat thought to himself, 'I am among the smallest of all animals and I don't stand a chance in making one of the twelve if the Cat will go.' So when the time came, the Rat left on his own without waking up the Cat, and was elected as one of the twelve Zodiac Animals.

When the Cat found out what the Rat had done, he was furious. The two became worst enemies. This is the reason why cats are not one of the twelve animals and they love to chase after rats.

Rates are prey for Cats. So Cats and Rates are enemies.

Cats and rats are predator and prey hence..they are enemies...part of food chain.

Very interesting question, but Iam unable to find the answer. May be it is because Cats love eating rats.

rats are favourite food of cats.

If they weren't so, who would have made Tom and Jerry?

It is a part of food chain.Rat is the food for cat and cat for dog and so on. It is nature.

Cannot have answer of this question. I think natural tendancy of cat and rat.

This is due to natural created by god. This is also a food chain in nature.

Don't know but I guess because the cats like their taste.

It's just the Animal Food chain.

Because their first alphabet are different...

I agree with suni51 they are not enemies actually cat cant stop itself when it see a rat because rat seems to be very tasty for cats..

He he.. Its natural. As other said, May be cats like to eat rat, favorite dish..

I guess nature made it that way ! Traditionally cats eat rats so rats are scared of them and it is only natural that they run away when they see rats and cats chase them and so on...
