Do you have to take out the male gerbil when a mother has given birth?

Yes, you absolutely must remove the male gerbil from the cage when the mother gives birth. Here's why:

* Infanticide: Male gerbils are known to kill their own pups. This is a natural instinct for them, as they would normally compete for resources within a wild population.

* Stress: The presence of a male can stress the mother, making it difficult for her to care for the pups properly.

Here's what to do:

1. Separate the male and female immediately after you notice signs of labor or after the pups are born. This will ensure the safety of the pups.

2. Provide the mother with a separate, quiet cage with a nesting box. This will give her space to care for her pups.

3. Keep the male gerbil in a separate cage. Don't introduce him back to the mother until the pups are at least 4 weeks old and have fully weaned.

Important Note: Even if you separate the male, it's essential to monitor the mother closely for any signs of stress or aggression towards her pups.
