Cat with Bionic Feet---If you like cats, you will LOVE this (No Cat jokes from my collegues)

From  BBC: Bionic feet for amputee cat (Click on the link for a 3 minute video)

""A cat that had its back feet severed by a combine harvester has been given two prosthetic limbs in a pioneering operation by a UK vet. The new feet are custom-made implants that "peg" the ankle to the foot. They are bioengineered to mimic the way deer antler bone grows through the skin.  The operation - a world first - was carried out by Noel Fitzpatrick, a veterinary surgeon based in Surrey. His work is explored in a BBC documentary called The Bionic Vet. The cat, named Oscar, was referred to Mr Fitzpatrick by his local vet in Jersey, following the accident last October. Oscar was struck by the combine harvester whilst dozing in the sun. The prosthetic pegs, called intraosseous transcutaneous amputation prosthetics (Itaps) were developed by a team from University College London led by Professor Gordon Blunn, who is head of UCL's Centre for Biomedical Engineering. Professor Blunn and his team have worked in partnership with Mr Fitzpatrick to develop these weight-bearing implants, combining engineering mechanics with biology.  Mr Fitzpatrick explained: "The real revolution with Oscar is [that] we have put a piece of metal and a flange into which skin grows into an extremely tight bone."  "We have managed to get the bone and skin to grow into the implant and we have developed an 'exoprosthesis' that allows this implant to work as a see-saw on the bottom of an animal's limbs to give him effectively normal gait." Professor Blunn told BBC News the idea was initially developed for patients with amputations who have a "stump socket". "This means they fix their artifical limb with a sock, which fits over the stump. In a lot of cases this is sucessful, but you [often] get rubbing and pressure sores."  The Itap technology is being tested in humans and has already been used to create a prosthetic for a woman who lost her arm in the July 2005 London bombings. "The intriguing thing with Oscar was that he had two implants - one in each back leg, and in quite an unusual site," Professor Blunn told BBC News.  He said that the success of this operation showed the potential of the technology.
"Noel has some brilliant ideas," he added. "And we're continuing to work closely with him to develop new technologies." The Bionic Vet is on BBC 1 at 2245 BST on Wednesdays...""
