But before he could make a third TV appearance he was chased off the scene by policemen.
Downing Street has a very long cat history going back over one hundred years, with one of the favourites being Humphrey who retired in 1997.
Prime Minister David Cameron moved into 10 Downing Street last summer with his family.

Officials say that there might be new plans to get a cat to deal with the fame hungry rat!
Experts reckon that there are about 50 million rats living across the UK.
