mating syrain hamster is very hard since they are solitary animals by heart. first make sure u have both hamster records in hand and u have a extra cage every day pick of the female around 5-10pm and stroke her back if she puts her tail up and stop moving she is in heat put her in a cage where neither male of female has been in this is called netural ground wait into they start showing signs of fighting and separte them
never leave them together for more than an hour sometimes if the male is too small or unhealthly she will rather painfully reject him by fighting with him!
