In Missouri the hunting season runs from the Saturday of Memorial Day weekend at the end of May until February 15 of the following year. Daily limit is 10 squirrels. From the MDC website...
"In gray squirrels, the mating period begins in late December or early January and again from late May to early July. Pregnancy requires about 45 days. Most litters are born in February or March, and July or August. A litter comprises 1–8 young, but 2 or 3 are most common. The young are hairless at birth, have their eyes and ears closed, and possess well-developed claws. They come out of the nest for the first time when 6–7 weeks old, and in another week or so they are weaned.
In fox squirrels, the cycle is similar, but they begin breeding 10 days to 2 weeks earlier than the grays."
