Coat and looks how to spot one

Wavy coat that turns plush

Babies have a wavy coat and curved whiskers. The waves start to straighten at about four weeks, and the adult coat looks plush, with a small kink at the tip of each hair. One copy of the gene looks the same as two.1

ColoursAny fancy mouse colour1

Personality what they are like

Coat type has no effect on character, so these are typical fancy mice: lively, curious and happiest with mouse company. With calm, gentle handling close to the ground they settle well and seldom nip, and the AFRMA expects every show mouse to be easy to handle.345

Daily activity how busy a day looks

Busy and quick, most active at night and around dusk and dawn. Offer a solid-surface wheel, ropes, branches, tubes and tunnels, and scatter part of the food so they can forage.467

Grooming and care the hands-on bits

No special grooming: mice keep themselves clean. Dust-free bedding and regular cleaning keep the coat nice.6

Home where they are happiest

A roomy, escape-proof cage with bar gaps under 5 mm, at least 2 cm of dust-free bedding plus paper or hay for nesting, hides with more than one exit, a solid wheel and climbing items. Keep it well ventilated, out of draughts and away from heat.6

Food basics what goes in the bowl

Complete mouse nuggets as the main food, with small portions of vegetables and fruit counted into the daily amount. Scatter some of the ration for foraging and provide fresh water from a bottle, checked daily.7

Company who they like around

Sociable animals that do best in stable, same-sex groups. Females usually live together easily; males are best kept with brothers they grew up with. Avoid swapping members in a settled group.83

The story where it all began

Caracul is one of several curly genes in mice. Breeders often combine it with other curl genes, because on its own it gives only gentle curls.19

Fun facts for the dinner table

  1. 1

    The caracul gene has 16 known versions (alleles).1

  2. 2

    Each caracul hair has a tiny kink right at the tip.1

  3. 3

    The waves start to straighten when the babies are only about four weeks old.1

  4. 4

    The gene's official name is keratin 71, a protein that helps shape hair.1

Owner questions the things everyone asks

How often should I feed my Caracul Mouse?

Feed your Caracul Mouse daily with complete mouse nuggets as the main food, plus small portions of vegetables and fruit. Scatter some of the ration for foraging and always provide fresh water from a bottle, checked daily.7

What should a Caracul Mouse eat, and which foods are dangerous?

Complete mouse nuggets should be the main diet, with small amounts of safe vegetables and fruit. Dangerous foods include chocolate, grapes, raisins, onion, garlic, avocado, and anything with xylitol. For a full list, ask your vet.710

Should I bathe a Caracul Mouse?

No, Caracul Mice keep themselves clean and do not need baths. Dust-free bedding and regular cage cleaning are enough to keep their coat nice.6

Does a Caracul Mouse need brushing?

No, Caracul Mice do not need brushing. They groom themselves, and their wavy coat stays healthy with proper bedding and cleaning.6

How do I look after a Caracul Mouse's nails and teeth?

Nail and teeth care varies by individual. Provide chew toys and a solid wheel to help wear them down naturally. Ask your exotic-pet vet for specific advice on trimming if needed.

How much space and exercise does a Caracul Mouse need?

Provide a roomy, escape-proof cage with at least 2 cm of dust-free bedding and plenty of climbing items. A solid-surface wheel, ropes, tubes, and tunnels will keep your mouse active. Scatter food for foraging fun.64

Should a Caracul Mouse live alone or with friends?

Caracul Mice are sociable and do best in stable, same-sex groups. Females usually live together easily, while males are happiest with brothers they grew up with. Avoid swapping members in a settled group.83

How long does a Caracul Mouse live?

Caracul Mice typically live between 1.5 and 3 years. With good care, they can enjoy a full, happy life within that range.234

Is a Caracul Mouse a good pet for children?

Caracul Mice can be good pets for children with calm, gentle handling close to the ground. They are lively and curious but seldom nip when handled properly. Always supervise interactions to keep both child and mouse safe.345

How do I hold a Caracul Mouse?

Hold your Caracul Mouse gently and close to the ground to make them feel secure. Use calm, slow movements and let them get used to your hands. Always supervise and never squeeze.345
