What Do Cats Purr For?
When it comes to knowing why cats purr, people offer up a number of different opinions. In most cases when people hear a cat purring they will automatically assume that this is because the cat is content. Certainly anyone who has the opportunity to allow a purring cat to sit on their lap will find the sound and the vibrations of it extremely comforting.
Kittens learn to purr from a very early age; around two days old. It is likely that their communicative purrs are limited during their first weeks so when kittens suckle and purr at the same time, the likelihood is they are purring out of happiness and satisfaction. Don not be fooled however, because all these positive emotions are not the only reason cats purr. Primarily purring is a form of communication and the ability appears in a large number of big cats and wild cats, too.
When a kitten purrs it is often a sign that they are happy with their lives. However, when around humans they can use it as decoy. Some kittens may purr as they cuddle up towards you, but be prepared when they suddenly decide it will be far more fun to try and bite you instead.
Purring, however, is a verbal skill cats use to suggest more than just happiness. During the years a cat matures, their linguistic capabilities improve and thus different purrs can indicate different moods and feelings. Purring of course still signifies happiness, but they might also purr to suggest fear and submission.
Also you may find that when a female is giving birth to a litter of kittens she may purr as they are being delivered. They may use this as a way of helping them to relieve some of the tension and pain they are feeling. Plus it may also provide them with reassurance and comfort. When it comes to cats purring, studies carried out have shown that it is quite common for those cats who are close to death to begin to purr as well. They feel that this type of purring is helping to create a more euphoric state in the animal or is as a result of the anxiety they are feeling.
Recent theories suggest that when cats release endorphins (also found in humans), they start to purr. Endorphins are released both when the cat is happy and when the cat is in pain, making it difficult to determine the precise reason a cat may be purring.
