Hamsters don't menstruate. However, female hamsters in estrus are prone to barking, their appetite is not very good, and they may bite the cage. In addition, female hamsters will secrete white liquid during estrus, and they will squat down in search of mating. If bleeding is found in the hamster's reproductive organs, it may be that the hamster is suffering from a reproductive organ disease or is infected by bacteria. Therefore, once this condition is discovered, it is recommended to send the hamster to a pet hospital for treatment immediately.
