Measure your guinea pig enclosure, compare its dimensions with Blue Cross guidance and check the essentials for a practical layout.
Setup checklist
How to measure the enclosure
Measure the continuous floor space inside the enclosure on one level. Leave upper levels and detached areas out of the main measurement. Measure a separate exercise run on its own.
How the comparison works
With a separate run, Blue Cross gives one main-enclosure reference for two females and a larger one for two males or three guinea pigs. For indoor housing without a separate run, it gives a larger footprint. The planner checks both sides as well as showing the area. The references are UK welfare guidance.
Does the result cover the entire setup?
The dimensions check is one part of planning. Review the checklist and leave enough room for movement after adding shelters, hay and water.
What if my group is different?
The tool still calculates the floor area. Consult local welfare guidance for your group and housing arrangement.
