Guinness the cat may be a city slicker but he's got a soft spot for one human that he's made friends with since he moved into his new apartment.

It all started for Guinness and the window cleaner when Guinness was just a kitten and started to interact with the abseiling window cleaner who comes to the building every week, but as the weeks and months went by, the two started developing a fun relationship and now, according to Guinness' owner Rina Takei, he waits every week for his 'Uncle' to appear at the window and say hello.

Adorable.
