Female eastern fox squirrels come into estrus in mid-December or early January then again in June. they normally produce two litters a year, however, yearling females may only produce one. Females become sexually mature at 10 to 11 months of age and usually produce their first litter when they are a year old.
Gestation occurs over a period of 44 to 45 days. Earliest litters appear in late January; most births occur in mid-March and July. The average litter size is three, but can vary according to season and food conditions.
Tree squirrels develop slowly compared to other rodents. At birth, the young are blind, without fur and helpless. Eyes open at 4 to 5 weeks of age and ears open at 6 weeks. Eastern fox squirrels are weaned between 8 and 10 weeks but may not be self-supporting until 12 weeks. Juveniles usually disperse in September or October, but may den either together or with their mother during their first winter.

“Although Samuel had a depraved imaginationperhaps even because of thislove, for him, was less a matter of the senses than of the intellect. It was, above all, admiration and appetite for beauty; he considered reproduction a flaw of love, and pregnancy a form of insanity. He wrote on one occasion: Angels are hermaphrodite and sterile.”
—Charles Baudelaire (18211867)
“Were I called on to define, very briefly, the term Art, I should call it the reproduction of what the Senses perceive in Nature through the veil of the soul. The mere imitation, however accurate, of what is in Nature, entitles no man to the sacred name of Artist.”
—Edgar Allan Poe (18091845)
