The Bible goes on to say that we have a duty to care for the world, including the animals in it. Animals are not ours to do with as we like. People are seen as caretakers of the natural world. We are made to live in caring relationships with God, each other and with the natural world. We are ultimately answerable to God who owns everything.
Many people feel uncomfortable about experiments involving the 'higher' animals like chimpanzees.
These animals have highly developed intelligence and language skills and display emotional behaviour that seems similar to humans. In the same way, people are disturbed by the thought of cats, dogs and rabbits being used in experiments. Animals which are less intelligent or attractive and which are not kept as pets arouse less concern. It is possible that chimps suffer in ways that lower animals such as mice do not. These higher order animals may experience more emotional types of pain, such as fear or anxiety, during experiments.
