What do you think you are? Part two

There’s growing scientific evidence that many animals are not only conscious but they possess a more profound sense of self. They can learn by experience and make decisions that depend on a sense of the future - in other words they are “sentient” beings with the capacity to feel pain, pleasure and emotions. In the second part of this two-part series, Sue Armstrong reports on the latest scientific research into the minds and consciousness of animals and the wider implications this has on our relationship with animals.
