🐹 Rex Guinea Pig

📊Overview

The Rex has a dense, very short, woolly coat with no guard hairs, giving it a soft, plush teddy-like texture and easy grooming. It looks similar to the Teddy but comes from a different gene, and its short coat offers less natural protection, so its skin and ears need occasional checking.

🧭Temperament & needs

📈Compared with other Guinea Pigs

🧠Personality & temperament

The Rex is widely regarded as one of the most laid-back and friendly guinea pig breeds, known for being mellow, even-tempered, and unusually tolerant of handling — which makes it a standout choice for families and children. It's sociable and playful, quick to come out and interact once it knows you, and rarely nippy or skittish. Its curious, gentle nature and moderate energy make it easy to bond with.

📜Origin & background

The Rex is a short-haired breed defined by a genetic coat mutation that produces dense, springy fur lacking guard hairs, giving it a plush, hedgehog-like texture. It's recognized by the British Cavy Council (though not the American ACBA) and is one of the larger guinea pig breeds, with adults among the biggest at the nose-to-rump range.

🏃Exercise & enrichment

A Rex enjoys daily floor time — at least an hour in a safe pen to run, popcorn, and forage — which suits its moderately active, playful temperament. Tunnels, chew toys, and scattered hay for foraging keep this smart, sociable pig entertained and prevent boredom-related stress.

✂️Grooming & hygiene

The Rex is the lowest-maintenance of these three: its short, dense coat has no long hair to tangle, so a gentle brush once a week (or even just occasional smoothing by hand) keeps it in great shape. Because its fur lacks guard hairs, avoid harsh brushing or frequent bathing that can dry the skin, and focus routine care on nail trims and cage hygiene instead.

🍽️Diet & feeding

Feed unlimited grass hay such as timothy as the mainstay of the diet, plus a small daily measure of plain fortified pellets and about a cup of fresh, vitamin-C-rich vegetables like leafy greens and bell pepper. As with every guinea pig, a reliable daily vitamin C source is critical since they cannot produce it themselves and are prone to scurvy.

🏠Housing & environment

Given that the Rex is a larger breed, provide a generous single-level cage — at least about 0.7 square meters for one and more for a pair — with soft, absorbent fleece or paper bedding and no wire flooring. Keep it in a calm spot at a stable cool temperature away from sun and drafts, and spot-clean daily, since clean, dry, cushioned flooring is especially important to protect its feet.

🩺Health & lifespan

Rex guinea pigs are generally robust but face the usual breed-wide issues: vitamin C deficiency (scurvy), dental malocclusion, respiratory infections, and skin problems like mites or fungus. Their larger body and dense, guard-hair-free coat make foot health and clean, soft flooring especially important to prevent bumblefoot. With good husbandry, diet, and vet care, they typically live around 5 to 7 years.

🎓Training & socialization

Rex pigs aren't trained like dogs, but their calm, confident nature makes them among the easiest guinea pigs to tame — with patient handling and treats they quickly learn to come when called, sit in your lap, and enjoy gentle interaction. A short, gentle acclimation period is usually all it takes for this trusting breed.

💰Cost of ownership

Initial costs cover a roomy cage, water bottle, hideouts, and starter supplies plus the pig itself — a moderate one-time outlay, with Rex pigs generally priced like other common short-haired breeds. Monthly upkeep for hay, pellets, fresh vegetables, vitamin C, and bedding is steady and affordable, while exotic-vet care is the main unpredictable cost to budget for.
