Drugs that are successful in animals can fail on humans. Studies show that 94% of the drugs tested on animals don't even work on humans (procon.org). Another problem is researchers may mislead end or ignore cures because they didn't work on animals. “Some chemicals that are harmful to animals prove valuable when used by humans. Aspirin, for example, is dangerous for some animal species, and Fk-506 (tacrolimus), used to lower the risk of organ transplant rejection, was ‘almost shelved’ because of animal test results, according to neurologist Aysha Akhtar, MD, MPH.” says procon.org. The biggest problem is how different animals are to us. Although some animals have similar DNA to us, it reacts differently. It's like playing the guitar, you may play Don't Stop Believing, by Journey, and Someone Like You, by Adele, you are using the same chords, but they are two very different songs. “The anatomic, metabolic, and cellular differences between animals and people make animals poor models for human beings.” states procon.org.
Even though animal testing helps create cures, animals not having long lives, and the tests possibly being able to help them, animal testing is a horrible thing. Vitro testing is a great alternative to animal testing, because of it being less expensive, being more reliable, and causing no cruelty. Another reason why animal testing is a horrid thing because animals suffer because the scientist don't know how safe the drugs are. Animals are also extremely different from humans so it flaws the
