Laboratory animals are animals used in scientific research to help understand biological processes, test new drugs, and develop medical treatments. Common species include mice, rats, rabbits, and monkeys. These animals are chosen for their genetic similarities to humans or their ability to mimic human diseases. The use of laboratory animals is regulated to ensure ethical treatment and minimize suffering. Researchers follow guidelines that promote humane care, including proper housing, nutrition, and veterinary care. The goal is to gather valuable data while respecting the welfare of the animals involved in the research process.
