Last year, Perseus the cat was brought to a veterinary clinic in the Greek town of Larissa. The poor, homeless kitty had suffered a terrible injury and he’d lost three of his legs. It was suspected he’d been hit by a car, or been caught in a car engine. Veterinarian Sofia Zoi wanted to help the little monopod. She worked with a team of designers and engineers, who came up with a high tech solution for Perseus. It wasn’t easy; cats themselves are feats of engineering.
