I'm so glad he's feeling better.
Now - a little story. Once upon a time, in Siam, the wicked jealous suitor kidnapped the beautiful princess and held her captive. Nobody knew wher she was, except her faithful and intellegent Siamese. He leapt upto/downto the place she was being held. The princess took off her angagement ring, put it on the cats tail and *snick* (ouch!) broke the tail so that it bent over and the ring would stay put. The cat went to the fiance, who recognised the ring and followed the cat back to rescue his fiancee, the princess.
So that is why some Siamese have a kink in the last half-dozen joints of their tail...........
......... or that is what the breeder of my late lamented Min told me. (Min, like many Siamese, had a kinked tail). She also charged me £60 instead of £90
So, if Keanu ends up with a kink you can tell the story but set it in Bengal instead!
