Ending1: Pick a size you're comfortable with. [substeps] Guinea pigs can have spaces in their cages where they can stretch out and rest. Ending2: This also includes accounting for the right dimensions for the cage to fit in the room or on the platform you plan on setting up with. [substeps] Have a tape measure and ways to mark off measurements such as tape or a sharpie handy. Ending3: This is because rabbits naturally like to be near the food and water bowls. [substeps] When you visit a pet store, ask if they would recommend a larger cage for the guinea pigs, which will allow them to move and explore more freely. Ending4: The cage must also be at least 4 to 6 feet (1.8 to 2.4 m) in height and width. The cage should offer two beds, one for each guinea pig and one for each animal.
