A cat called Mayor Stubbs is celebrating 15 years in charge of the town of Talkeetna, Alaska.

Stubbs was elected mayor as a joke by the town's 900 residents just after he was born, and has been in charge ever since.

He does all the things mayors are supposed to do, selling the town to outside investors by appearing in local and national magazines and news articles, meeting the voters as they visit him in the local shop, and receiving official correspondance in the form of cards and letters from wellwishers.

Stubb's job comes with some perks - food and a ceremonial chalice (a wine glass with his name written on it).

The town's unusual choice of mayor has made it something of a sensation in the US.
