During the festivities we often forget the amount of stress and sometimes injuries both external and internal that we might cause them unknowingly.
Unlike us humans, animals tend to react and behave differently to noise, cracker pollution, colours and extreme light exposure.
Many of us do not know that a human's hearing frequency range differs from animals, therefore during Diwali celebrations, bursting of crackers might end up hurting animals and causing them stress, fright, chaos etc.
