No. 10: Sphynx. A suede-like coat is the sphynx's most unmistakable feature, but he's also curious, smart and a clown who craves applause for his antics. In fact, he loves attention so much that you may want to consider getting him a fellow sphynx playmate. (Photo by Quentin Descotte)

“At her job, Maria Torero cares for sick human beings. At home, she lavishes love on slowly dying cats – 175 of them at last count. The 45-year-old nurse has turned her two-story, eight-room apartment into a hospice for cats with feline leukemia, scattering it with scores of feeding dishes and at least two dozen boxes litter boxes. Some have suggested she shelter healthy cats instead. “That's not my role”, she told The Associated Press. “I'm a nurse. My duty is to the cats that nobody cares about”. She said that “people don't adopt adult cats, especially if they are terminally ill”. – Franklin Briceno via Associated Press. (Photo by Martin Mejia/AP Photo)

The claws are out for North Korean dictator Kim Jong-un and Russia's Vladimir Putin – as cats now able to use a model of him as a scratching post. And moggies can also maul at Russian president Vladimir Putin, whose face also features on the new cat toys which are 1.5ft tall and cost £4,500. They are made from hessian rope, and 3D-printed faces are then attached to the posts, before they are handpainted. The toys took a team of artists 200 hours to finish. (Photo by The Pussycat Riot)
