If it’s a baby squirrel, it won’t be able to survive on its own. You need to nurse it till it’s four to five months old. It needs fruit juices and small bits of fruit and baby food. You can also prepare a juice for it at home by adding one teaspoon of salt and three teaspoons of sugar in one-fourth cup of lukewarm water. The baby squirrel has to be fed every hour. Also, since the baby can’t control its body temperature, you need to keep it in a box lined with thick, warm blanket, but do not cover the box with the lid. With your help, it will survive.
