An ingenious scientist created a homemade ladder so his beloved cat can travel freely in and out of his house after his landlord banned him from having a catflap. Tariq Khoyratty, 26, made the 7m ladder, which is 15cm wide, for less than £25 from four 6ft decking planks and strips of wood. His girlfriend Nikki Wheeler, 26, came up with the idea after their estate agent banned them from fitting a catflap to their 17th century Grade II listed cottage's back doors. Since building and installing it on Saturday, October 8, their five-month-old ginger tom cat called Nelson has been constantly running up and down wooden structure. It is attached to the couple's first floor bedroom window with an easily detachable elastic bungee cord.
