Small pets may be tiny, but the industry supporting them is anything but small. The global guinea pig cage market is currently valued at $455 million and projected to surge to $715 million by 2033, while rodent accessories overall are forecasted to double to $2.5 billion in the same timeframe. While millions of U.S. households own guinea pigs, rabbits and other small animals, species-specific data is limited. And, safe, high-quality habitats remain an overlooked gap in the broader pet economy.
