Since I've started writing about cats I've had to delve into their biology and some of it makes strange reading.
For instance, while not color blind (cats can see the blue/green spectrum) they have problems with reds and yellows. This is because they have sacrificed some of their color vision in order to have better night vision - better than ours, that is. Their smell and hearing is better than ours too.
But when it comes to their sex life ... It's well known that toms have a barbed penis (ouch!) which is why the females yowl so horribly during mating when the males withdraw. It is supposed to stimulate their ovaries and help fertilisation, but I can't help thinking there could have been some less painful way of going about this. Or maybe all female cats are masochists? Who knows.
Part of the fascination of cats is that they are so very 'other' - tame enough to enjoy our company yet alien in many ways. A relative of mine once sort-of tamed a feral cat, a real bruiser of a beast who used to sit on her landing and stare malevolently when I tried to pass. In appearance and temperament he seemed so removed from my own cuddly, fluffy little moggy that they might have been a different species.
I've really enjoyed writing my 'feline romance' and the end is in sight, so watch this space if you are interested in reading it.
