Here's why:
* Territoriality: Male gerbils can become fiercely territorial, especially during breeding season. They might see the females and pups as a threat to their dominance.
* Hormones: Male gerbils have high testosterone levels, which can contribute to aggressive behavior.
* Stress: Introducing a new female to a male's cage or having too many gerbils in a small space can cause stress, leading to aggression.
* Competition: The male might see the pups as competition for resources like food and space.
What can you do?
* Separate genders: The safest option is to keep male and female gerbils in separate cages. This is especially important during breeding season.
* Introduce carefully: If you are introducing a new gerbil to a group, do it slowly and carefully. Monitor their interactions closely.
* Spacious enclosure: Provide a large enclosure with plenty of hiding places, toys, and food sources to reduce competition and stress.
* Observation is key: Be alert for signs of aggression, such as hissing, chasing, or fighting. If you see any aggression, separate the gerbils immediately.
Remember: Gerbil behavior can be unpredictable, and it's always best to err on the side of caution to ensure the safety of your gerbils. If you're unsure about anything, consult a veterinarian or experienced gerbil breeder for advice.
