The significance of laboratory animals is evident in three key areas: biomedical research, product safety testing, and education. Biomedical researchers heavily rely on animals to expand their understanding of the human body, diseases, and health processes. Animals are also essential in developing new vaccines and treatments for various diseases, benefiting both humans and veterinary techniques. The industry utilizes animals to test the effectiveness and safety of consumer products like cosmetics, cleaning products, pesticides, chemicals, and drugs. In the field of education, animals play a crucial role from elementary to college level. They are utilized in teaching processes such as dissection in science classes or for medical students learning surgical techniques. Additionally, scientists study animals to gain insight into specific species’ history, psychological behavior, social behaviors, and skills.
However, keeping animals captive can result in unnatural pain due to unfamiliar environments. Numerous organizations advocate for minimizing or replacing procedures that cause pain to animals during research or testing. Rats and mice make up the majority (85-90%) of animal subjects used in research, education, and testing; other studied animals include rabbits , guinea pigs , hamsters , dogs , cats ,and non-human primates . The choice of animal for research depends on the subject being studied with most rats and mice specifically bred for this purposeIn addition, half of the dogs and cats utilized for research are specifically bred for this intention. The remaining animals are obtained from accredited animal dealers who are required to adhere to the care standards mandated by the USDA-regulated Animal Welfare Act.
The three main categories of alternative methods, known as the three Rs (Replacement, Reduction, and Refinement), encompass various approaches. Replacement involves substituting animals in testing. This can be achieved through absolute replacement where animals are completely replaced or relative replacement where only cells and tissues are used instead of the whole animal. However, replacing animals is not always feasible.
In order to minimize pain and improve comfort for animals undergoing testing, scientists strive to reduce their suffering. The practice of replacement has now become commonplace. In the past, if a woman wanted to determine whether she was pregnant, she had to visit a laboratory for a test that involved killing a rabbit. Nowadays, she can purchase an over-the-counter kit that tests for certain chemicals.
Computers provide an advanced form of replacement by offering alternatives to traditional methods such as dissecting real live frogs. Computer models can be used instead, which is my personal preference! Additionally, there is a growing trend towards using volunteers as test subjects for new facial and skin products.
Reduction, the second method, involves sharing research animals. For instance, if one scientist conducts a study on the lungs of a sheep, when it is time to sacrifice the sheep, they will permit other scientists to utilize its kidneys, liver, or heart.
Refinement, as the third option, aims to reduce an animal’s pain and suffering. One way to achieve refinement is by using less aggressive techniques that are gentler on the animal. Instead of invasive procedures, researchers can choose non-invasive methods like ultrasound or MRI to understand the internal condition of the animal.
In recent years, significant progress has been made by the cosmetics industry in moving away from animal testing. Many companies have reduced their reliance on whole-animal testing by 80 to 90%, and some have completely eliminated it. Since the 1980s, numerous companies have invested substantial resources into finding alternatives to animal testing.
Most ingredients used in today’s products have already undergone animal testing and proven their safety. Different types of tests are conducted, including chronic-toxicity tests that assess long-term effects at low levels of exposure, and acute-toxicity tests that evaluate risks from short-term contact with eyes, skin, or ingestion.
One test that caused controversy in the 1980s was the Draize eye test involving rabbits to determine a substance’s irritative or damaging properties on the eye. This test consisted of applying a solution to one eye of a rabbit and observing changes compared to the untreated eye over a week. However, there has been an 87% reduction in the number of eye irritation tests conducted since then.
The protest in 1980 led to significant changes in the cosmetics industry, resulting in increased efforts to develop non-animal alternatives. Many companies have completely stopped using the Draize test. In parts of Europe, the LD50 test, which estimates the lethal dose for 50% of test animals, has been banned and is no longer supported by the EPA. There are various arguments against animal testing, including concerns about its morality, necessity, and validity. Advocates for animal rights argue that animals have their own right to life and should not be used for experimentation. Additionally, some believe that relying on animal testing is unreliable due to physical and mental differences between humans and animals. Furthermore, it is argued that keeping animals in artificial environments cannot produce reliable results.
There are multiple arguments in favor of animal testing, including considerations of morality, necessity, and validity. The primary concerns of this perspective are the need to protect and improve quality of life for humans. While supporters of animal testing may care for animals, they do not place them on an equal scale as humans. Research on animals is deemed necessary for various reasons, such as developing vaccines, treatments, and cures for diseases. It also ensures that new products do not cause harm to humans, as there have been instances where safety testing was not mandated by law and people suffered.
Animals serve as ideal research subjects because they share biological similarities with humans and experience many of the same health issues. Some animal species serve as good models for human health and physiology. For example, our knowledge of the immune system largely comes from studying mice while our understanding of the cardiovascular system has been advanced by studying dogs. Additionally, animals have shorter life cycles compared to humans allowing scientists to study them throughout their entire lives and manipulate certain environmental factors like diet, temperature, and lighting.
While some argue that animals can be replaced in research, many supporters still believe that animals cannot yet be completely replaced.
Animal experimentation has brought about numerous benefits for both animals and humans. It has played a vital role in the advancement of various cures, treatments, techniques, and medicines. Veterinary medicine has particularly benefited from animal research, with advancements made in treating diseases like rabies and distemper. Ongoing efforts are focused on combating illnesses such as AIDS and Alzheimer’s disease. Moreover, studying the nutrition, housing requirements, and social behavior of animals helps improve their care conditions. Additionally, certain studies contribute to habitat restoration and conservation efforts for different animal species.
The phrases “Cruelty-free” and “Not Tested on Animals” can have varying interpretations depending on the company since they lack government regulation. When a product claims to be “Not Tested on Animals,” it may mean that the final product itself was not tested on animals but its ingredients underwent animal testing. For instance, while a red lipstick may not have been directly applied to an animal during testing, colorless lipstick could have been used instead. Alternatively, it could signify that although the company avoids conducting animal testing themselves, they purchase ingredients from other companies that do perform such tests.
The FDA mandates animal testing for pharmaceuticals and other products, with the exception of cosmetics and toiletries. Nevertheless, these items still require non-animal testing to ensure customer safety. This is when you may come across labels such as “cruelty-free” or “not tested on animals.” All human-use products, including drugs, vaccines, cosmetics, shampoo, personal care items, food packaging, household cleaners, pesticides, chemicals, fabric treatments and more must undergo testing prior to being sold. To support the abolition of animal experimentation and promote awareness: educate yourself about it; teach others about the three Rs (Replacement, Reduction and Refinement); share this information with friends or those in charge; consider writing letters to Congress urging enforcement and endorsement of the ICCVAM Authorization Act. The Interagency Coordinating Committee on the Validation of Alternative Methods (ICCVAM) validates newly developed alternatives through government channels.

If you are not old enough to vote, you still have the power to make a difference. Speaking out is important, but it’s not enough to just protest animal abuse. We need to educate and inspire young scientists who care about these issues and have a deep understanding of them. These scientists will play an active role in finding and using alternative testing methods that don’t harm animals. You have the ability to bring about this change.
