Guinea Pig
(Cavia porcellus)
Basic Information:
Guinea pigs, also known as cavies, are gentle, social rodents native to the Andes mountains of South America. They are herd animals by nature and thrive in the company of their own kind. Guinea pigs are known for their expressive squeaks, whistles, and chirps, which they use to communicate with both humans and other guinea pigs. Their small size, friendly temperament, and relatively simple care requirements make them one of the most popular small mammals kept as pets.
Lifespan:
5–8 years in captivity with proper care.
Sexing:
Males (boars) and females (sows) can be visually sexed, though young guinea pigs may be more difficult to distinguish.
Enclosure:
Guinea pigs have fragile spines and poor depth perception, so usable single-level horizontal floor space is far more important than vertical multi-level height. Wire-bottom cages must never be used, as they cause painful foot sores and infections (bumblefoot/ulcerative pododermatitis).
Enclosure Size:
Pair of Sows (Females): Absolute minimum of 7.5 sq. ft. (e.g., standard 30" x 36" cage), though 10.5 sq. ft. (a standard 2x4 C&C cage, ~30" x 56") is strongly recommended.
Pair of Boars (Males): Minimum of 10.5 to 13 sq. ft. (2x4 or 2x5 C&C cage). Boars require substantially more space to establish non-aggressive territories and prevent fighting.
Accessories: Provide at least two distinct hideouts (one per pig, each with multiple exit points to prevent cornering), hay racks, tunnels, and untreated wooden chew items.
Substrate:
Fleece Bedding: Wicking polar fleece placed over an absorbent underlayer (such as washable puppy pads, U-Haul moving pads, or disposable pee pads) is the gold standard for low dust, high comfort, and cost-effectiveness. Spot-sweep daily and wash weekly with unscented detergent.
Shavings: Kiln-dried aspen or dust-free, non-scented paper bedding. Never use cedar or untreated pine shavings, as their aromatic phenols cause severe respiratory irritation and liver damage.
Lighting & Temperature:
Maintain a 12-hour light/dark cycle using natural room light or indirect lighting.
Ideal room temperature should remain between 65–75°F. Keep the enclosure away from drafts, direct sunlight, heaters, or air vents to prevent stress or illness.
Food:
Guinea pigs are strict hindgut fermenters and require an uninterrupted, high-fiber intake to maintain digestive motility and keep their open-rooted, continuously growing teeth trimmed down.
Grass Hay (80%+ of Diet): Unlimited, 24/7 access to clean, dust-free grass hay (such as Timothy, orchard grass, or meadow hay). Alfalfa hay should be avoided for healthy adults due to excessively high calcium and protein content.
Vitamin C: Cavies lack the enzyme L-gulonolactone oxidase and cannot synthesize their own Vitamin C. Deficiency results in scurvy.
Daily Fresh Source: Offer roughly 1 cup of fresh vegetables daily per pig, prioritizing bell peppers (green, yellow, or red—high in Vitamin C, low in calcium).
Tablets: Give a stabilized, plain chewable Vitamin C tablet (e.g., 25–50 mg daily) or Vitamin C treat.
Caution: Avoid overfeeding high-calcium greens (like kale, spinach, or parsley) to prevent painful bladder sludge and urinary stones.
Pellets: 1/8 to 1/4 cup daily per adult pig of plain, high-fiber, timothy-based pellets fortified with stabilized Vitamin C. Avoid colorful seed, nut, or dried fruit muesli mixes, which promote selective feeding and choking hazards.
Socialization:
Group Dynamics: Guinea pigs are obligate herd animals and should never be kept alone. Always house them in bonded pairs or small single-sex groups (or a neutered male with one or more females). Isolation leads to lethargy, chronic stress, and behavioral withdrawal.
Handling: Always support both the chest and hindquarters with two hands when lifting; never pick a guinea pig up by the scruff or around the abdomen alone. Daily supervised floor time in a secure, pig-proofed area provides essential exercise and mental enrichment.
Breed Care & Grooming:
Short-Haired Breeds (American, English, Abyssinian): Low maintenance; require only occasional light brushing and monthly nail trims.
Long-Haired Breeds (Peruvian, Silkie/Sheltie, Texel): Require daily brushing with a wide-tooth comb and regular hygiene trims around the hindquarters to prevent matting and soiling from urine and feces.
All Breeds: Require regular nail clipping every 3–4 weeks and routine monitoring of weight, incisor wear, and foot health.
With their curious nature and relatively simple care needs, Syrian hamsters make excellent pets for responsible children and adults alike. Their independent personalities and nighttime antics are a joy to observe, making them ideal for quiet households.
