Guinea pigs are highly social animals whose welfare is often compromised by solitary housing and inadequate space. Meeting their social and environmental needs is essential for their wellbeing.
Most commercially sold guinea pig cages are far too small for these active, social animals. Solitary housing causes measurable stress — lone guinea pigs show higher cortisol levels, reduced activity, and increased stereotypic behaviours. Inadequate vitamin C intake leads to scurvy, a painful and preventable condition. Dental disease from improper diet is also common. Despite being popular children's pets, guinea pigs are often misunderstood as low-maintenance — in reality, they require daily care, social housing, and significant space. Welfare education at the point of sale and improved retail standards could significantly reduce suffering.
