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)

Merit Prize Winner: “A Well Earned Rest in the Sahara”. This photo of Moussa Macher, our Tuareg guide, was taken at the summit of Tin-Merzouga, the largest dune (or erg) in the Tadrat region of the Sahara desert in southern Algeria. Moussa rested while waiting for us to finish our 45-minute struggle to the top. It only took ten minutes of rolling, running, and jumping to get back down. The Tadrat is part of the Tassili N'Ajjer National Park World Heritage area, famous for its red sand and engravings and rock paintings of cattle, elephants, giraffes, and rhinos that lived there when the climate was milder. Photo location: Summit of Tin-Merzouga, Tadrat, Tassili N'Ajjer National Park, Algeria. (Photo and caption by Evan Cole/National Geographic Photo Contest)
