A MARRIED COUPLE who share their city apartment with their pet puma say that they consider the big cat a part of their family. Sergey and Marina Ross, both aged 32, live with their 2-year-old mountain lion, Irma in their apartment in central Moscow. They adopted Irma from a zoo one year ago, after hearing that they intended to put her down because they could no longer afford to keep her. The big cat initially did not allow Sergey or Marina to touch her – but after months of adjusting to her new surroundings, she has eventually learned to love and trust them. Now, the couple have regular cuddles with the 38kg cat and Sergey says that he sometimes even sleeps next to her.
