It's Caturday!
Celebrate your caturday with these kittehs!
Prionailurus planiceps - the Asian flat-headed water cat
Habitat: Wetlands and flood plains in Malaysia and neighbouring regions of south-east Asia
A cat with webbed feet? A cat that's happy to hang out in water? A stump-tailed, flat-headed cat that swims expertly and dines almost exclusively on fish? Such an animal exists - but it's on the last of its nine lives. Only cloning might give it another.
Everyone knows that domestic cats hate water: readers who own one and have tried to give it a bath will be painfully aware of the fact. But the flat-headed cat of south-east Asia throws what everyone knows out the window. An enthusiastic swimmer, more like a feline otter than a cat, it has various adaptations to an aquatic lifestyle.
However, despite its frolicking nature this elusive animal is severely threatened by habitat loss. Saving it from extinction might require a newly developed form of cloning.
Although about the same size as the familiar domestic cat, flat-headed cats have short stumpy tails, and their eyes are strikingly large. They split from the other seven major cat groups around 6 million years ago, but there have been few studies of them in the wild, and what we know about their behaviour is mostly guesswork based on their body design (PDF).
Here's what is known or guessed. As the name suggests, their heads are noticeably flattened compared with other cats - perhaps to streamline them for their life in the water.
The feet are partially webbed. A relative, the fishing cat, also has part-webbed feet, but the flat-headed cat's are far more flipper-like. In fact, when a kitten was captured in Malaysia some years ago, its keepers found that it would play for hours in a basin of water. From what's been found in the stomachs of dead animals, it seems their diet was mainly fish, with the odd shellfish and frog thrown in.
Brave new kittens
Classified by the International Union for Conservation of Nature as "endangered", extreme measures may be required to save it.
A new kind of cloning technology called intergeneric nuclear transfer could be the answer. The technique works by taking a nucleus from a skin cell of the animal to be cloned and transferring it into an emptied egg cell of a different, commoner species.
African wild cats have been born after developing in the eggs and wombs of domestic cats, and it may be possible to grow water buffaloes using the eggs of cows.
The technique, currently being attempted by Thai geneticists, could allow flat-headed cats to be grown in the lab, without the need for a breeding pair.
Arabian Sand Cats - the Hobbits of the Cat world
Meet the Cincinnati Zoo's newest little Arabian Sand Cat kittens, who just debuted to the public today. Born on October 29th, the kittens, male "Najah" and female "Fath," currently weigh just 1lb. 12 oz. and 1 lb. 6 oz. respectively.
The kittens' parents are a specially selected breeding pair from the Al Wabra Reserve in Qatar. Sand cats have fur on their feet to walk on hot sands and dig their own burrows to make nests and avoid the heat of the desert. <--TOTALLY HOBBITS!
And finally, a Cat With Cat-Shaped Spots on its back:
