Common Name: Mixed Breed Guinea Pig
Scientific Name: Cavia porcellus (domesticated guinea pig species)
Origin: Result of crossbreeding between different recognized guinea pig breeds (e.g., American × Abyssinian, Peruvian × Silkie, etc.)
Recognition: Not a standardized breed by cavy associations (like ACBA or ARBA), but very common as pets and rescues
Size: 20–30 cm (8–12 in)
Weight: 700–1,200 g (1.5–2.6 lbs), though larger mixes can reach up to 1.5 kg
Coat: Highly variable depending on parent breeds:
Short and smooth (like American)
Rosetted and coarse (like Abyssinian)
Long and flowing (like Peruvian or Silkie)
Mixed coats (medium-length, wavy, or uneven growth)
Colors & Patterns: Any possible—solid, bicolor, tricolor, agouti, roan, brindle, or spotted
Lifespan: 5–7 years on average; some live up to 8–9 years with excellent care
Personality: Just as friendly, vocal, and social as purebred guinea pigs
Social Needs: Thrive in pairs or herds—should never be housed alone
Temperament: Varies by individual but generally affectionate, curious, and easy to tame
Grooming Needs: Depends on coat type
Short coat: low maintenance
Long coat: requires regular brushing to prevent tangles
Communication: Use the same wide range of sounds—wheeks, purrs, rumbles, and chirps
Type: Strict herbivores (same as all guinea pigs)
Staple Diet:
Unlimited hay (timothy, orchard grass, or meadow hay)
Fresh vegetables daily (leafy greens, bell pepper, cucumber, carrots, etc.)
Guinea pig pellets fortified with Vitamin C
Vitamin C Needs: Essential (20–30 mg daily); without it, they can develop scurvy
Treats: Small pieces of fruit (apple, orange, kiwi, strawberry) in moderation
Maturity: 2–3 months old
Gestation Period: 59–72 days
Litter Size: 2–4 pups on average
Young: Born fully furred, eyes open, and able to eat solid food almost immediately
Note: Breeding mixed breeds is discouraged unless carefully planned—rescues are often full of unwanted guinea pigs
