Is a rodent mammal, measuring between 35 and 45 cm in length, of which almost half belong to the tail. On the front limbs, the thumb is reduced, but the other 4 fingers are well developed and endowed with long, curved and sharp nails. Squirrels are sometimes considered pests due to their propensity to chew various edible and inedible objects, and their stubborn persistence in trying to get what they want. Their characteristic feature of gnawing also helps them keep their teeth sharp, and because their teeth grow continuously, this prevents their overgrowth. Sometimes, squirrels chew even through plastic and metal, to get to the food.
