It's often said that pets and their owners can start to look alike, but these adorable photographs take the old mantra to a new extreme. They are the work of Svetlana Valyiskaya (27), from St Petersburg, who snaps pets in everyday poses in her spare time from her job as a commercial photographer. The vibrant costumes and scenes, which Svetlana designs herself, have made the photos a hit in her native Russia – and it's not hard to see why. She said: “I really love animals, they are loyal, faithful and true and always interesting to work with – plus they never criticise the photographs afterwards”.
