* Hamsters are prolific breeders: Female hamsters can get pregnant multiple times a year, and they can have large litters.
* Males can be aggressive: Male hamsters can become aggressive towards females, especially after they have mated. They may even attack and injure the female or the babies.
* Females can become stressed: Females can become stressed by the constant presence of a male, which can lead to health problems.
* Risk of infanticide: In some cases, male hamsters may even kill their own offspring.
Important Note: If you have a mixed-sex group of hamsters, it's best to separate them immediately to prevent unwanted pregnancies.
Here are some additional tips:
* Separate males and females into different cages.
* Make sure the cages are large enough for each hamster to have its own space.
* Provide plenty of enrichment, such as toys, hideaways, and tunnels, to help your hamsters stay happy and healthy.
If you have any further questions about hamster care, please consult a veterinarian or a qualified pet expert.
