An adult female house mouse (Mus musculus) can deliver a litter every 20-22 days. The young reach sexual maturity (that is the males can impregnate females and the females can get pregnant) at approximately 10-12 weeks. The newborn pups begin to get ';fuzzy'; at 7 days, open their eyes at 11-12 days and are usually fully weaned (no longer nursing) at 19-21 days.Is 7 weeks enough for a pair a mice to breed, give birth and have a little fur come in?
If they are sexually mature mice, then yes they can mate, give birth, and the mice will grow hair in less than 7 weeks.Is 7 weeks enough for a pair a mice to breed, give birth and have a little fur come in?
Yes it is.
