Here's why:
* Space is important: Guinea pigs need ample space to move around, play, and explore.
* Height matters: While the floor space is important, they also need enough vertical space for climbing and jumping.
Here's a general guideline:
* Minimum: A cage that's at least 7.5 square feet of floor space is considered the minimum for two guinea pigs.
* Ideal: A cage with 10 square feet or more is ideal for two guinea pigs, especially if they are active.
* Height: The cage should be at least 18 inches high.
Your Cage:
* Your cage measures 1176 square inches (42 x 28).
* This is about 8.2 square feet, which is closer to the minimum requirement.
Before you decide:
* Consider the height: If your cage is only 18 inches high, it might be a bit cramped. Aim for at least 24 inches for better enrichment.
* Activity level: If your guinea pigs are very active, a bigger cage is always better.
* Consider cage accessories: The more space you have, the more enrichment you can add with things like hideaways, toys, and tunnels.
Recommendation:
It's possible that your cage could work for two guinea pigs, but it's definitely on the smaller side. You can always make it more spacious by adding a second level or a large playpen for them to explore.
