Admetus on the video is a young, quiet, grey cat. He is played by the same actor as the one who plays the Great Rumpus Cat. George was a quiet, young, white and black cat has two distinctive patches over his eyes, one brown and one black. He left the London show, where he was played by the same actor as the one who played the Great Rumpus Cat, on 21st October 2000. He is no longer there since the actor playing him, Steven Wayne, had been with the cast since 1981 and had played George for 13 years (that could also be why George was not on the video). He did the mating dance with Victoria, played one of Growltiger's pirates and was a good friend of Victor. He has also appeared in international versions of the show.
Admetus is the video version of George since they look alike and become the Great Rumpus Cat. Pouncival is his name in the 2014 London production at the Palladium, but he looks almost identical to George.
