Why we have tails.....

 Why do we have tails? Because they are beautiful, of course. Look at these two splendid top tails with their long thick covering of fur.

As well as being elegant, they are very useful indeed for balancing and climbing. When we are up a tree we can use our tail as a counterbalance. If we are walking along a narrow wall, for instance, if we lose our balance and our body lurches to the right, our tail will immediately swing to the left to re-balance us.

Cats that have lost their tail in an accident or are born without one like Manx cats, find balancing much harder. For an animal that spends time in trees, it's obvious that the tail is an important help to climbing.

We also use our tail to express our feelings - though that is a different blog. 

So what is the anatomy of our tail - well there are somewhere between 19 to 23 vertebrae with six pairs of muscles which can pull the tail from side to side, up and down, and twist it at any point. Compare the dog's tail wagging sideways and moving up and down, but the tail itself just moves from the base. It cannot twist itself half way.

As for humans... no tail at all and therefore about eighteen fewer vertebrae. No wonder they have poor balance, inability to express themselves except by vocalisation.

And a complete lack of elegance.

Our secret language of scent

We can leave messages for other cats, and reminders for ourselves, with a secret language - a specialised scent called a pheromone. This is a chemical emitted from glands in own bodies among other places from our cheek and chin.

Ever thought why we cats rub our chin and cheek against something? We are marking it with this pheromone and with our own ordinary body scent (a kind of signature mix). 

If we have rubbed against our human, then that scent of human will also be there. We are making our household territory friendly by making it smell of the family - us, our humans and perhaps another resident cat (if we like him and have rubbed against him too.)

It is like a post-it note to ourselves saying "We live here: this is our home and family." Humans cannot smell this at all: nor can they usually see it.

Occasionally, if we have rubbed in the same place for a long time, our human may notice a sort of dark mark. If they are houseproud, they clean it off. This is very upsetting.

So we have to re-mark it all over again. And again.
