Sheba or Sheba Mini Yak

The Sheba is a longhaired, rosetted cavy, characterised by mutton chop whiskers, with frontal, presented to one side of the face, and in a naturally tousled appearance. They have been recognised as a cavy breed in Australia. Their breed standard was developed by Wynne Eecen (considered to be the breed's founder by Australians) in the 1970s, and was published in her book Pigs Isn't Pigs. Genetically, these animals are similar to Abyssinians, Peruvians, Shelties & Ridgebacks. They are also known as the "Bad Hair Day" Cavy.
