Coat and looks how to spot one

short, smooth, silky coat with a single forehead crest

Picture a sleek English Self guinea pig, short broad head, big bold eyes and drooping petal ears, then add one neat whorl of hair on the forehead. The crest is the same colour as the rest of the coat, which sets it apart from the American or White Crested, whose crest is a contrasting white. The coat itself is short, soft and glossy.126

ColoursAny standardised Self colour (as for the English Self), with the crest matching the body12

Daily activity how busy a day looks

Guinea pigs are busy animals that can be on the go for up to 20 hours a day, napping in short spells. Offer daily time in a larger, safe run or room with tunnels, hides and things to explore. Contented guinea pigs often leap and twist in the air, a habit owners call 'popcorning'.43

Grooming and care the hands-on bits

The short, smooth coat needs only a light brush now and then to stay neat; show animals are groomed so the coat is clean and free of stray guard hairs.12

Home where they are happiest

A roomy enclosure tall enough for them to stand up on their hind legs, with solid floors and a deep layer of dust-free bedding rather than wire grids. Provide one more hiding place than there are guinea pigs. Indoors aim for about 17-20 C; protect them from heat above about 26 C and bring outdoor guinea pigs inside when it falls below about 15 C. Spot-clean daily and do a full clean at least weekly.7

Food basics what goes in the bowl

Good-quality hay available at all times should make up most of the diet, plus fresh grass where possible. Add a daily portion of grass-based guinea pig pellets and a daily mix of fresh vegetables and herbs such as parsley, bell pepper, celery, cucumber and romaine. Guinea pigs cannot make their own vitamin C, so it has to come from food every day. Fruit only as an occasional small treat, and fresh water always available.843

Company who they like around

Very sociable: guinea pigs should live with at least one other friendly guinea pig and do best in pairs or small groups.47

The story where it all began

Guinea pigs were domesticated in the Andes of South America and reached Europe with traders in the 1500s, where they became popular pets. The English Crested was developed by British fanciers as a crested version of the English Self, keeping the crest in the body colour. Crested cavies were also crossed with the Sheltie in the 1970s to create the long-haired Coronet. Today it has a full British Cavy Council standard alongside the contrasting-crest American Crested.3129

Fun facts for the dinner table

  1. 1

    Its crest must match the body exactly: any odd-coloured hairs in it lose points on the show table.1

  2. 2

    The crest alone is worth 20 of the 100 show points.1

  3. 3

    It is the self-coloured counterpart of the American (White) Crested, whose crest is white.2

  4. 4

    Under the crest, it is judged like an English Self, one of the classic smooth show breeds.1

Recognised by the official bits

British Cavy Council
Full breed standard: judged as 80% of the English Self standard (head, eyes and ears 24, body 20, colour 24, coat 12) plus 20 points for the crest. The crest must be a deep, even rosette radiating from a pinpoint centre between the eyes and ears, its lower edge well down the nose; an open centre or differently coloured hairs in the crest are penalised.1

Owner questions the things everyone asks

How often should I feed my English Crested Guinea Pig?

Hay should be available all day, every day, as it makes up most of the diet. Offer a daily portion of grass-based pellets and a mix of fresh vegetables and herbs each day. Furry Diary's starting plan includes a daily hay refill and fresh vitamin C-rich veg.843 Furry Diary plan

What should an English Crested Guinea Pig eat, and which foods are dangerous?

Feed unlimited good-quality hay, daily grass-based pellets, and a mix of fresh vegetables like bell pepper, cucumber, and romaine. Avoid dangerous foods such as chocolate, avocado, onions, garlic, grapes, raisins, and anything with xylitol.84310

Should I bathe an English Crested Guinea Pig?

Bathing is rarely needed and can stress them; spot-clean their coat instead. If a bath is absolutely necessary, ask your exotic-pet vet for safe guidance.

Does an English Crested Guinea Pig need brushing?

Their short, smooth coat needs only a light brush now and then to stay neat. Show animals are groomed more thoroughly to keep the coat clean and free of stray guard hairs.12

How do I look after an English Crested Guinea Pig's nails and teeth?

Furry Diary's starting plan suggests trimming nails every 28 days and checking teeth weekly. Overgrown nails or teeth need a vet's attention; never try to trim them yourself without guidance. Furry Diary plan

How much space and exercise does an English Crested Guinea Pig need?

Provide a roomy enclosure with solid floors and deep bedding, plus daily time in a larger safe run with tunnels and hides. They are active up to 20 hours a day and love to explore.743

Should an English Crested Guinea Pig live alone or with friends?

They are very sociable and must live with at least one other friendly guinea pig, ideally in pairs or small groups. A lonely guinea pig can become unhappy.47

How long does an English Crested Guinea Pig live?

They typically live between 4 and 8 years. With good care, a healthy diet, and regular vet checks, they can enjoy a full lifespan.435

Is an English Crested Guinea Pig a good pet for children?

They can be wonderful for gentle, supervised children, as they are busy and fun to watch. However, they need careful handling and a calm environment, so adult guidance is important.

How do I hold an English Crested Guinea Pig?

Always support their whole body with one hand under the chest and the other under the hindquarters, keeping them close to your body. Never pick them up by the legs or scruff.
