Our team knows that guinea pigs with sensitive stomachs need a clean, stress-free environment. A cage thatโ€™s hard to clean or poorly ventilated can lead to health issues. We compared the most affordable options on the market, focusing on materials, ease of assembly, and floor space. We looked for cages with smooth surfaces that are easy to wipe down, ample ventilation to reduce ammonia buildup, and safe materials. After evaluating dozens of models against published standards and aggregated owner feedback, weโ€™ve narrowed it down to the five best budget-friendly cages that wonโ€™t upset your guinea pigโ€™s digestion.
