Baby squirrels are tiny and very fragile, but their mother’s instinct is very helpful. The baby squirrels solely depend on their mother until they are old enough to move without their support.

When do squirrels have babies? Squirrels have babies twice a year. It occurs once between December and February and once more from late June to early August. Female squirrels deliver their young either in August to September or February to April, with the gestation period lasting 38 to 46 days.

Mothers know best! Interestingly, this is also applicable to most mammals, including squirrels. The mother squirrels know exactly what to do with their babies, and through this guide, you will be amazed at how they take care of them. On the other hand, you will be shocked to learn how some males treat baby squirrels.

Where Do Squirrels Build Their Nests?

Both leaf nests and tree cavity dens are forms of nests built by squirrels.

Tree cavity dens are either natural or woodpecker-made holes in older trees. Squirrels love this style of nest because it protects them from the cold. Although they are used throughout the year, tree cavities are most frequently sought out when winter approaches.

Leaf nests are formed in the limbs of trees for extra stability and at high altitudes to remain unseen. The squirrels gather little broken twigs, leaves, and dried grass to make these nets. It is constructed with a single entrance and exit point, just like dens.

Squirrels start to mate once they are 10 – 12 months of age. At this point, they are now sexually mature and are ready to mate. Male squirrels may mate any time of the year, but most females become fertile every start of the year, either in January or February. During this time, females will attract males and will choose among them.

Squirrels have some interesting mating habits, which include males chasing the females. This scene may be mistaken for playing, but actually, females are testing the males if they are suitable for them. In most cases, males fight each other to win a female’s heart, and the older ones are likely to have an advantage.

A baby squirrel is called a kit or kitten but is also sometimes called a pup. They are usually 1 inch long and weigh about 1 ounce only.

How Many Babies Can a Squirrel Have?

How Many Babies Can a Squirrel Have?

On average, a mother squirrel can have 2 – 5 kittens in one birth. However, some squirrels may have 9 babies in a single birth.

How Do You Know if a Squirrel Has Babies?

How Do You Know if a Squirrel Has Babies

If there’s a squirrel in your attic and it refuses to leave no matter how hard you scare the animal, there’s a huge chance that it has babies with her. In most cases, you may even hear the baby squirrels crying for milk. This is also why you should check the attic thoroughly before driving a squirrel out of your house. 

Outdoors, you can easily identify a mother squirrel and another female with no babies yet. From a distance, a breastfeeding mother can be seen with elongated nipples that are going up and down while they are moving. Also, the skin around their nipples has already lost its fur. Young females usually have a flat chest.

Why Do We Never See Baby Squirrels?

You will never see baby squirrels because they stay in their nests under their mother’s care until they can survive independently. For tree squirrels, their nests are in the trees, usually six feet above the ground. But unfortunately, some baby squirrels fall to the ground, and this is the only time you are likely to see them.   

It is also very unlikely to see babies of ground squirrels because they stay in underground dens with their mothers. These dens could be between 3 and 6 feet deep, and baby squirrels are still too weak to get out of their own. Ground squirrels are social animals, so lots of mother squirrels stay together in one den.

Do Squirrels Come Back to the Same Nest?

Squirrels come back to the same nest but only the adult ones. On the other hand, juvenile squirrels will never return once they leave their nests.

Do Squirrels Carry Their Babies in Their Mouths?

Squirrels carry their babies in their mouths, but only the mothers do it.  Female squirrels carefully hold their babies by the scruff (back of the neck) when they move them from one place to another. Amazingly, sleeping baby squirrels don’t wake up. They also do this if a baby falls to the ground from their nest.

Do Mother Squirrels Abandon Their Babies?

What Do Squirrels Do With Their Dead Babies?

What Do Squirrels Do With Their Dead Babies?

Currently, no records prove that squirrels bury the dead bodies of their own babies or eat them. But unfortunately, some squirrels kill baby squirrels and eat them. This untoward event is called infanticide, in which tree squirrels and ground squirrels were said to have been doing this for a very long time.

A study suggested that male tree squirrels kill the babies of other males because they want to mate with the mother. Killing the babies will shorten the lactation of the mothers, thus leading them to enter into estrus, the stage where females are in heat. Meanwhile, this phenomenon is said to be rare in ground squirrels.

What Is the Average Lifespan of a Squirrel?

What Is the Average Lifespan of a Squirrel

Gray squirrels may live up to 20 years in captivity but may only live for 11 – 12 months in the wild due to the presence of predators such as foxes. On the other hand, fox squirrels live up to 18 years in captivity and only 10 years in the wild.
