What is a Guinea Pig like?
Guinea pigs, also known as cavies, are social rodents originally from South America. They are calm, communicative animals that vocalise readily and often become relaxed around familiar people.
They come in many coat types, from smooth-coated to rosetted and longhaired varieties, but all need company, hay, vitamin C and steady handling.
Guinea Pig temperament
Guinea pigs are usually calm, sociable and rarely aggressive. They do best in same-sex pairs or small groups and can become withdrawn if kept alone.
Guinea Pig care needs
- Keep guinea pigs in pairs or small compatible groups.
- Provide unlimited hay for gut and tooth health.
- Offer vitamin C-rich vegetables daily.
- Use a large indoor enclosure with plenty of floor space.
- Provide hides, tunnels and daily interaction.
- Spot-clean daily and deep-clean regularly.
Guinea Pig size and lifespan
Adults usually weigh 700g to 1.2kg and measure 20cm to 30cm. Average lifespan is 4 to 7 years, with some individuals reaching 8 years with excellent care.
Guinea Pig housing and environment
Guinea pigs are best kept indoors in the UK where temperature and damp can be controlled. They need a large floor-level enclosure with low-dust bedding, hiding places and no steep ramps.
Diet and nutrition
Hay must be available at all times. Daily leafy greens and vitamin C-rich foods such as pepper, kale and parsley are important, with pellets measured and sugary foods avoided.
Handling and socialisation
Support the whole body when lifting and handle low to the ground. Calm daily sessions help build confidence, especially with school-age children supervised by adults.
Is a Guinea Pig right for me?
Guinea pigs suit owners wanting a gentle, interactive but low-key pet. A pair needs daily food prep, regular cleaning and a budget for dental, urinary or respiratory vet care.
