Good question! As an animal technician my main role is to keep the animals in good health and provide them with all they need to keep their standard of living high and make them happy. We call this keeping high welfare standards. We provide food, water, enrich their cage with toys, tubes,chew sticks and bedding. We may be involved in putting males and females together for mating. We will wean the litters from their parents, look after the colony of animals and some of us get involved in experiments with these animals. But our main role is being a care giver to the animals so that they are happy in the lab environment and so can give us better scientific results.
