Animal Testing

Pros and Cons of Animal Testing


  • Animal experiments have played a critical role in just about every medical breakthrough of the last century.
  • They are vital for testing the safety of drugs and vaccines, from common painkillers to advanced anti-cancer treatment.
  • They may not be perfect, and human trials are also vital, but without them medical advances would be seriously hampered
  • Cancer, strokes, heart disease, diabetes, Parkinson's and Alz-heimer's are just some of conditions for which animal experiments have benefited research.


  • Animal advocacy groups contend that the biological, emotional, and cognitive similarities between humans and other animals make the practice of using animals in experiments unethical.
  • In animal testing, countless animals are experimented on and then killed after their use.
  • Others are injured and will still live the remainder of their lives in captivity.
  • Animal testing generally costs an enormous amount of money, as the animals must be fed, housed, cared for and treated with drugs or a similar experimental substance.
  • There is also the argument that the reaction of a drug in an animal's body is quite different from the reaction in a human.
