How to Tell the Age of a Squirrel
To determine the age of a squirrel, first determine whether it is orphaned. If it is orphaned, you should leave it alone and wait for its mother to return. If the baby is not orphaned, you should wait until it has reached a suitable age to venture out on its own. If it is an adult, you can safely handle it. You can use the following methods to gauge the age of a squirrel.
To determine a squirrel’s age, observe its appearance. In the first few days after birth, a baby squirrel is pink and hairless. Its ears are flat to the head, eyes are shut, and its fur is very thin. At one to two weeks, it develops grayish fur that covers its entire body. By three to four weeks of age, the lower incisor teeth have emerged.
Generally, a squirrel can be identified by its ears. They open at about three to four weeks of age. If the squirrel does not have ears, it is older. If the animal has teeth, it is about three to four weeks old. However, a squirrel does not grow teeth until around three or four and a half weeks of age. You don’t need to know the exact age of a squirrel to feed it. If you don’t know its age, it is important to contact a wildlife rehabilitator.
Another way to determine the age of a squirrel is to check its physical development. Juveniles develop at different rates and are more dependent on their caregiver than adults. You can also check the squirrel’s physical maturity to see how old it is – this can help you decide whether to feed it or keep it. Regardless of its age, knowing how old it is will be useful if you plan on feeding a squirrel.
It is possible to tell the age of a squirrel by looking at its teeth. During the first six weeks, a squirrel will still have no teeth. The lower incisors will not appear until 3 to four weeks, and the upper incisors will be visible by about four and a half weeks. If the eyelashes are not fully formed, the squirrel is only three to four weeks old.

During the first two weeks of life, a squirrel is still a baby. It has no teeth. This means that it is still a baby. A baby squirrel will not be fully weaned until around 10 to 12 weeks. Unlike baby birds, a squirrel requires more attention and care than a baby bird. It is vital to know the age of a squirrel if you want to save it from harm.
A baby squirrel will not have teeth at this point, but will still have eyes at this stage. A baby squirrel will have no teeth until it is about eight to ten weeks of age. At this stage, a squirrel is fully grown and ready to move around. Depending on the age of a squirrel, you will need to give them extra food. A healthy adult can live for more than 10 months.
The fur of a baby squirrel will continue to grow until it reaches the age of about six weeks. At this stage, it has no eyes. The eyes will grow in at least three weeks, and the ears will have a distinct pattern. In the following weeks, the baby will be completely self-sufficient, and it will have teeth as well. If the baby is still a baby, you should avoid it until it matures.
Besides the eyes, a squirrel will also have white fur on the underside of its tail. At four weeks of age, it is about five weeks old, and it will have eyes. The eyes will be open by the time it is eight weeks old. The body will develop teeth in the same manner as it grows in humans. In addition, you will be able to tell the age of a squirrel by looking at its growth and development patterns.
