Animal sentience and welfare needs utmost importance as animal sentience is the capacity to feel pleasure and pain whereas, welfare would be intimately connected with the physiological stress response and it would simply be a matter of finding a reliable indicator of stress. Sentient animals are aware of their feelings and emotions. Animals also enjoy positive and negative emotions from carrying out natural behaviour. These could be negative feelings such as pain, frustration and fear. Sentient animals have complex social lives involving communication, organized groups and family bonds, the disruption of these relationships can severely damage animal welfare - Separating bonded individuals like a mother and infant can cause the animals to protest and despair. Sentience like feelings can be measured directly or indirectly by the methods such as preference testing, motivational testing and understanding animal communication. However, sentience as a science have limitations like anthropomorphism, cognition and demonstrating its existence at a scientific level is that the concept relates to a being‘s own thoughts, feelings and emotions. From, this study it may be concluded that animal sentience is imperative for improving animal welfare and attitudes towards animals.
