My female hamster attacks male after breeding. Should I separate?

Updated On September 23rd, 2025

Pet's info: Small Animal | Unknown - Small Animal | Female | unspayed | 20 days old | 35 lbs

I’ve read some of that website but before they had sex they didn’t fight but when they had sex 2 she attacks him and what do you think I should do leave them overnight tonight or not?

If they are fighting a lot now, I would separate them. She clearly does not want him around. And you do not want her or him to get hurt. This is normal behaviour for a female pregnant hamster. Best separate them.
