A cat learns a whole bunch of communication signs as soon as it is a kitten.It is important to know their meaning so that you are not mistaken when you want to assess your cat's mood! 

Eyes and Ears

The shape of the eyes and the position of your cat's ears are precise indicators of what he wants to express.-If the ears are held straight, open forward and the eyes appear round, your cat is in a neutral attitude, without any particular emotion.

On the other hand, if the ears are open forward but blinks quietly, with the pupil slit, be sure your cat is relaxed and happy.-An angry cat is holding its ears erect, turned to the sides, with frowning eyes.

When the ears are lying backwards, with the pupils round and dilated, your cat is obviously afraid of something. He may also be trying to intimidate an opponent, or even signal to you that he will not take long to react firmly. Warning !

Whiskers

Whiskers are very important for cats: they are used to explore their environment and communicate with their peers. They should therefore never be cut.

Body Movement

Unlike the dog, a cat which wags its tail does not express its satisfaction. This gesture shows on the contrary that the cat is very angry. If you pet your cat and he starts wagging his tail, it's best to stop right away because he doesn't like it and tries to tell you!When your cat rubs its head or tail against your legs, it usually means that it feels good around you and wants to share its scent with you. He's imbibing you with soothing pheromones for him. Do not confuse this behaviour with asking for food. Just respond to his hug.

If you can learn to decode the behaviour and the language of your cat, know that it is very sensitive to your attitudes and your intonations, more than to the words which you use. He can sense your emotions and even anticipate what you are going to do. 

No wonder he often guesses that you want to take him to the vet and he goes into hiding!!!
