Rex Guinea Pig

The Rex Guinea Pig is best known for its short, dense, curly coat that covers its entire body. It resembles the Teddy Guinea Pig in having a curly coat, but the Rex's fur has a coarser, wirier texture. With a sturdy, compact build and a generally calm temperament, Rex Guinea Pigs tend to bond well with their people and are considered friendly toward handling. They're rated beginner-friendly, making them a good choice for first-time guinea pig owners. Rex Guinea Pigs typically live 5 to 7 years and reach an adult size of about 20 to 30 cm and 800 to 1300 grams. Their distinctive curly texture makes them a charming, easygoing companion for the long haul.

About Rex Guinea Pig

The Rex Guinea Pig has a short, dense curly coat and a sturdy, calm temperament, making it a beginner-friendly breed. It lives 5-7 years and reaches 20-30cm and 800-1300g as an adult.

7 things to know before welcoming a Rex Guinea Pig

  1. 1Caring for the curly coat

    The Rex's coat is short and dense, with a coarser, wirier texture than the Teddy Guinea Pig's. Daily brushing isn't essential the way it is for long-haired breeds, but regular brushing helps manage shed hair and debris caught in the curls and keeps the skin underneath in good condition.

  2. 2A sturdy, solid build

    Rex Guinea Pigs have a sturdy, solid build, reaching about 20 to 30 cm and 800 to 1300 grams as adults. When holding one, support its body firmly and avoid awkward grips or drops given its solid frame.

  3. 3A calm, people-friendly nature

    Rex Guinea Pigs are generally described as calm and relatively easy to bond with. That said, individual personalities vary, so give a newly welcomed pig time to settle in and build trust gradually rather than handling it heavily right away.

  4. 4Beginner-friendly, but not hands-off

    Being rated beginner-friendly means the Rex Guinea Pig is manageable for someone with basic guinea pig care knowledge, not that it requires no effort. Proper housing and a consistent feeding routine are still essential day-to-day care.

  5. 5A 5-7 year commitment

    With a lifespan of 5 to 7 years, the Rex Guinea Pig is a longer-term companion than many small animals. Before bringing one home, think ahead about whether your living situation can support consistent care for that whole span.

  6. 6A hay-based diet

    Guinea pigs can't synthesize their own vitamin C, so a hay-based diet needs to be paired with guinea-pig-specific pellets and vitamin C-rich vegetables. Keep fresh hay and water available at all times.

  7. 7Prepare housing before arrival

    Set up a cage sized for its sturdy build and a space where you can manage temperature before bringing your Rex Guinea Pig home. Since coat type can affect heat regulation, pay attention to seasonal temperature control — cooling in summer and warmth in winter.
