Space: Guinea pigs are social animals and thrive in groups. However, you need enough space. A general rule of thumb is at least 7.5 square feet of floor space per guinea pig in a cage.
Compatibility: You need to make sure the guinea pigs are compatible. It's best to introduce them slowly and supervise them carefully at first. It's also crucial to consider their sex and age, as female guinea pigs can be more aggressive than males.
Housing: The cage needs to be large enough and safe. There should be plenty of hiding places, toys, and fresh hay.
Other Factors:
* Socialization: Guinea pigs need to be socialized with other guinea pigs.
* Health: A crowded cage can lead to stress, fighting, and health issues.
* Cleaning: A larger cage with more guinea pigs will require more frequent cleaning.
If you are considering getting multiple guinea pigs, it's essential to do your research and ensure you can provide a spacious, safe, and enriching environment for them.
Remember, responsible guinea pig ownership includes providing them with adequate space, proper care, and a suitable social environment.
