How old are pet shop syrian hamsters?
I am not sure the age they are sold, but: Generally for female hamsters, the ideal age to start breeding is at 4-6 months – any younger and you would risk her having a poor litter (she has still to grow herself) and also increase the likelihood of cannibalism. Leave it any longer than 6 months and you run the risk of birth complications. For male hamsters, they are sexually active from as young as 6 weeks of age but it’s probably best to leave them alone till they’re about 2-3 months old before contemplating breeding from them. Dwarf hamsters kept together will start breeding at 2-3 months of age.
