Rabbits have been used in scientific research for many years, primarily in the fields of medicine, pharmacology, and toxicology. Rabbits are often used in research because they are relatively small, easy to handle, and have a similar physiology to humans in some respects.

In medicine, rabbits have been used to study cardiovascular diseases, respiratory diseases, and reproductive disorders, among other things. In pharmacology, rabbits are commonly used to test the safety and efficacy of new drugs, and to determine the proper dosage and administration of drugs. In toxicology, rabbits are used to assess the potential toxicity of various substances, including chemicals, drugs, and environmental pollutants.

Rabbits are also commonly used in research related to the development of medical devices, such as stents and heart valves, and in the testing of surgical procedures and techniques.

It is worth noting that animal research, including research involving rabbits, is highly regulated and subject to strict ethical guidelines. Animal welfare is a top priority in research, and procedures are in place to minimize any pain or distress that animals may experience during experimentation. In addition, researchers are required to consider alternatives to animal research whenever possible and to ensure that any animal research conducted is necessary and scientifically valid.
