My hamster mom is losing hair. Should I separate her 3-week babies?

Updated on September 23rd, 2025

Pet's info: Small Animal | Unknown - Small Animal | Female | unspayed

My hamster has a spot of hair gone. She has babies and they mess with her. They might be ready to leave their mom because they are 3 weeks old but they mess with her and now her hair is lost. Should I separate them or just see what happens?

Hamsters can be weaned from mom around 3-4 weeks of age. This may be a good idea if they are overgrooming or "bothering" her. The hair loss may also be due to stress.
You should also separate male and female pups (hamster babies ) from one another since hamsters can breed as early as 3 weeks of age.
If the hair loss persists or if the hair does not grow back, have the mother examined by your veterinarian.
