Cats
lost a degree of genetic diversity in order to produce consistent conformation. In 1997/98 a
curly-tailed Turkish Van was reported. A Singapura with an unusual tail was reported in 2002.
The tail was described as very flexible and he could curl it round. It is not like American
Ringtails, as it does not curl as much, nor does it curl up and over. It is held low and curled in
a loop at his side. An American Keuda with a similar tail ("Curlietail") was reported at around
the same time. She double curled the tail when she sat down, but at 5 months old she does not
curl it as much. Again, it would appear that flexibility is lost as the cat matures. Since the
establishment of a breeding programme, it seems that curly tails of varying degrees are more
frequent that initially suspected. What was once seen as a fault now has a serious following.
Curled tails have also turned up in Russian Blues, Siamese/Orientals, Ocicats, Persians,
