A couple built a fully-insulated luxury house for their neighbourhood stray cat and now he sleeps there every night.<br /><br />Chris, 35, and Danica Gadeken, 31, first noticed the moggie about three years ago when he was just a kitten.<br /><br />They lost sight of him for about a year before he reappeared last year, only this time much larger.<br /><br />As winter approached in Lincoln, Nebraska, USA, Chris and Danica became concerned for the cat, who they affectionately named Fat Billy.<br /><br />As Fat Billy was too skittish to be officially adopted and welcomed into their home, they decided to build him a luxury house in their yard.
