The black cat has already proved he has luck on his side.

When he turned up at Launceston's RSPCA Care Centre about two months ago, he was as thin as a rake and nicknamed Starvin-Marvin.

``He was really thin and incredibly hungry,'' centre manager Lorraine Hamilton said.

``He couldn't get enough food into him.  He would eat it all really quickly just in case there wasn't any more.

``He wasn't sociable and his fur was mangled.''

Marvin had been found as a stray and had no microchip or tag.

``If he hadn't been found and brought to us when he was, he wouldn't be alive,'' Ms Hamilton said.

Now after no owner has turned up and he is healthy again, Marvin is up for adoption.

Ms Hamilton said he was ``a very handsome cat now'' and had made best friends with a tabby cat at the shelter called Slinky.

Almost 20 cats are available for adoption at the Launceston RSPCA and are waiting to have their lucky day.
