Right now, millions of mice, rats, rabbits, primates, cats, dogs, and other animals are locked inside cold, barren cages in laboratories across the country. They languish in pain, ache with loneliness, and long to roam free and use their minds. Instead, all they can do is sit and wait in fear of the next terrifying and painful procedure that will be performed on them. The stress, sterility and boredom causes some animals to develop neurotic behaviors such incessantly spinning in circles, rocking back and forth and even pulling out their own hair and biting their own skin. They shake and cower in fear whenever someone walks past their cages and their blood pressure spikes drastically. After enduring lives of pain, loneliness and terror, almost all of them will be killed. This is supposed to introduce the topic without taking sides, but this is sadly what animal testing has become.
A lot of medical steps for wards has happened through the years thanks to animal testing, and the outcome has both helped humans and animals. But besides that we have made a lot of medical wonders,animal testing is still used for example cosmetics which isn't very important (even if some people think so).
During the experiments is the animals often suffering in tiny cages with old water and disgusting food. There is also very many ways to experiment without animals, so there is no need for using it any more.
