Common questions
Where do these numbers come from?expand_more
The figure for a pair follows RSPCA Australia guidance, which says two guinea pigs need an enclosure of at least 2 m × 0.5 m (1 m²). The other figures come from Humane World for Animals, converted to square metres. See our size guide for the full sources.
Do lofts or second levels count?expand_more
No. Only flat, continuous floor counts toward the minimum. Levels and ramps are extras for enrichment.
Does daily floor time mean I can use a smaller cage?expand_more
No. Floor time is great enrichment, but guinea pigs spend most of their lives in their cage, including every night, so the cage should meet the guidance on its own.
