Despite having the lights on, your guinea pig does not rely on its eyesight for movement. It is because guinea pigs have relatively poor vision despite having large eyes.
Guinea pigs are entirely comfortable in complete darkness and will not let the dark hinder their movement or other activities.
Its whiskers are designed to be exquisitely sensitive and will aid the guinea pig in feeling its way around. A powerful sense of smell guides recognition and interaction with any nighttime companions.
When the lights are off, they do not need a nightlight since they need periods of complete darkness. Guinea pigs need light and darkness for their physiological well-being.
