If you want to help a squirrel that is not moving, the first and foremost approach is putting on thick gloves and using a thick towel to prevent biting. Pick and place the squirrel in an open box and on something warm, e.g., a bottle of hot water wrapped in a towel. If it’s your squirrel and you are sure it’s sick, your reptile veterinarian is the best person to reach out to. For abandoned squirrels, quickly seek a wildlife rehabilitator intervention.
