Pingu and Humbug were orphaned at four weeks old when their mother disappeared. They were found and taken to the RSPCA where Sally cared for them until they were old enough. Pingu and Humbug learned to use a litter tray, play with toys, and were given operations so they could not have kittens. Now that they are older, Pingu and Humbug live and work at the RSPCA as happy cats with identification collars and microchips.
