Silkie Satin Guinea Pig

Cavia porcellus

Also called Silkie Satin, Sheltie Satin, Satin Silkie

Recognised breedShort profile

From Domestic guinea pigs come from South America. The satin coat is a recessive mutation that, according to Omlet, was established in America before reaching the UK in 1986; the satin Silkie combines it with the Silkie coat type.12

Coat and looks how to spot one

long, smooth, backward-sweeping coat with a satin sheen

The Silkie Satin has the Silkie's long, smooth coat that all grows backwards: the mane starts behind the head and flows over the shoulders and body with no parting, leaving the face clear and making a teardrop shape seen from above. In the satin form the coat has a lustrous shine all over and an even silkier feel. The satin coat comes from a recessive gene: the hairs are finer and more see-through than normal (Wikipedia describes thinner, more translucent shafts, while Omlet and other guides describe them as hollow), so light passes into them and the coat gleams.453526

ColoursMany self (solid) coloursSatin forms of other colours and patterns, such as agouti and dalmatian, are also bred2

Personality what they are like

Owners describe satin guinea pigs as very friendly and playful. Like all guinea pigs they are gentle, vocal companions that are happiest with a friend of their own kind.27

Daily activity how busy a day looks

Guinea pigs are busy little animals that can be up and about for much of the day and night, resting in short naps. Give daily time in a larger safe run or room with tunnels, hides and new things to explore. A happy guinea pig may jump and twist in mid-air, a move owners call 'popcorning'.71

Grooming and care the hands-on bits

The long coat needs daily care: brush gently in the direction the hair grows, working through the sweep and sides. Many pet owners trim it to a manageable length and keep the hair around the rear short so it stays clean. Plenty of hay keeps companions busy so they leave each other's long hair alone.85

Home where they are happiest

Provide a roomy enclosure tall enough to stand up on the back legs, with solid flooring and a deep layer of dust-free bedding instead of wire. Offer one more hiding spot than there are guinea pigs. Indoors around 17-20 C is comfortable; keep them away from heat over about 26 C and bring outdoor animals inside when it drops below about 15 C. Spot-clean daily and do a full clean at least weekly.9

Food basics what goes in the bowl

Hay should be available at all times and form most of the diet, with fresh grass when possible. Add a measured daily portion of grass-based guinea pig pellets and a handful of fresh vegetables and herbs. Guinea pigs cannot make their own vitamin C, so their daily food must supply it. Keep fruit as a small occasional treat and always provide fresh water.1071

Company who they like around

A very sociable animal that should live with at least one other friendly guinea pig; pairs or small groups suit them best. In the wild, cavies live in close family groups.79

The story where it all began

Guinea pigs were domesticated in the Andes of South America thousands of years ago and later reached Europe, where fanciers began breeding them for coat and colour. The satin coat, with its finer, light-catching hairs, was developed by American breeders and arrived in Britain in 1986. Today the ACBA recognises satin versions of five breeds, and the Silkie Satin is judged on the Silkie standard with the added requirement of an even sheen over the whole coat.52113

Fun facts for the dinner table

  1. 1

    The Silkie Satin's hair all sweeps backwards from the head, so unlike the Peruvian Satin its face is never covered by a fringe.4

  2. 2

    Satin hairs are finer and more translucent than ordinary guinea pig hair, which is what lets the coat catch the light and glow.6

  3. 3

    The satin trait is recessive, so a satin baby needs to inherit the satin gene from both parents.5

  4. 4

    According to Omlet, satin guinea pigs first appeared in America and were brought to the UK in 1986.2

  5. 5

    British Cavy Council satin standards set aside 20 of the 100 points just for 'satinisation', the strength and evenness of the sheen.4
