How Are Squirrel Babies Born? 
If you’ve ever wondered how squirrel babies are born, then you’ve come to the right place. These adorable animals produce two litters a year, the first one in the spring and the second one in the summer. A litter can contain anywhere from two to five young. Upon birth, squirrel babies are blind and toothless. They don’t leave their nest until they’re eight or twelve weeks old, when they have opened eyes and are strong enough to get back to their nest.

Female squirrels mate multiple times a year
Mating in a female squirrel’s territory occurs at least twice a year, and it is a highly competitive process. Male squirrels will run after female squirrels and compete with one another to become a female’s mate. Mating occurs within a few days, and each female squirrel chooses the most dominant male. Once mating has taken place, the male squirrels leave, leaving the female to care for her young.
Male squirrels will gather near the territory of a female squirrel while she is in estrus and wait for her to become receptive. If she is pursued, she will scurry away or violently defend her territory. Once she is ready, the female will engage in a mating chase within her territory. The dominant male will find the female and initiate the process, which takes between one and 25 minutes.
They build a nest in a hollow tree
Squirrels give birth at a variety of times throughout the year, depending on the species. They begin courtship by chasing each other frantically and give birth to two or five babies. After the babies are born, the mother takes care of them and weans them at ten or twelve weeks. At this point, the mother drives the young away to feed in other areas and may raise another litter before the end of the year.
Squirrels can mate at any time of the year, though the male doesn’t participate in the rearing of the young. A female usually lines her nest with soft material before giving birth, after which she has a six-week gestation period. The female will typically give birth to one or two babies per year during the breeding season. During the nesting season, the female may build another nest, which will hold the new born babies.
Baby squirrels are born naked, blind, and toothless
Newborn baby squirrels are naked, toothless, and blind. They weigh between three and four grams and are completely naked. The fur covering the underbelly will grow in two to three weeks. At six to eight weeks, the baby squirrel can sit up on its own and begin chewing on solid food. At ten weeks, it will have fur covering most of its body, a bushy tail, and is sexually mature.
These adorable creatures stay in nests that their parents build for them. They are often higher in trees than other animals, so they’re out of reach of predators. Unlike humans, squirrels mature much faster than we do. The average squirrel will be an adult by eight to ten weeks of age. Squirrels have a short lifespan and mature quicker than humans. Their young reach sexual maturity at eight to ten weeks old. Compared to their peers, they can turn 90 degrees in the air.
They mature into adults in 4-6 weeks
The first signs of a squirrel baby are a low-set set of front teeth and open ears. They are also covered in fuzzy gray fur and have a white belly and legs. At three or four weeks of age, the tail hair and body hair grows longer. These new babies are covered in a thick, white coat. This fur can be found on their head, belly, legs, and tail. The tail hair grows longer, and the baby squirrel will have an adult-like tail at about six weeks of age.
The baby squirrel will resemble a typical adult squirrel by about eight to 10 weeks of age. At this age, it will become very active, using its sharp claws to climb and hang upside-down. By 10 weeks, it has a full tail and bushy tail and fully developed teeth. If you’re thinking of rescuing a squirrel, don’t forget to document its care so that no one else takes it home!
Precautions to take to protect your home from squirrels
The first step to protecting your home from squirrel babies is to seal any openings they can enter. If possible, install fitted screens on windows and doors. If you have open vents or chimney tops, place wire mesh on these areas. Consult a pest management professional about other ways to seal your home’s defense. It’s best to seal the most obvious entry point first. Make sure your home is well-insulated and that no food sources are available to squirrels.
Squirrels are likely to enter your home for the same reasons as other rodents: food, warmth, and a nesting area. If they can find an entry point, they’ll enter. Check your exterior and foundation for holes, and trim overhanging tree branches. If you’re not sure a squirrel has made it into your home, keep an eye on it and prevent it from becoming a problem.
