* Different diets: Guinea pigs are herbivores with specific dietary needs, while rabbits are also herbivores but with different requirements. They shouldn't share the same food.
* Different social structures: Rabbits are social animals that often live in groups, while guinea pigs are less social and prefer smaller groups or solitary living.
* Size and dominance issues: Rabbits are often larger and more dominant than guinea pigs, which could lead to bullying and aggression.
* Health risks: Rabbits can carry diseases that can be harmful to guinea pigs, and vice versa.
* Stress and anxiety: Even if the animals tolerate each other initially, the constant presence of a different species can cause stress and anxiety, leading to behavioral issues.
Instead of keeping them together:
* It's best to keep guinea pigs with other guinea pigs and rabbits with other rabbits.
* Provide separate cages, enclosures, and food sources for both species.
* If you want to introduce them, do it slowly and under supervision, with a safe barrier between them.
* It's crucial to research and understand the specific needs of each species to ensure their well-being.
Remember, responsible pet ownership involves providing a safe and comfortable environment for each animal, respecting their individual needs.
