Rabbits don't wear make up, dogs don't smoke.
Each year, more than 115 million animals—including mice, rats, frogs, dogs, cats, rabbits, hamsters, guinea pigs, monkeys, fish, and birds—are used in laboratory experiments around the world each year.
These animals are used in laboratories for biology lessons, medical training, curiosity-driven experimentation, and chemical, drug, food, and cosmetics testing. Before their deaths, some are forced to inhale toxic fumes, others are immobilized in restraint devices for hours, some have holes drilled into their skulls, and others have their skin burned off or their spinal cords crushed.
In addition to the torment of the actual experiments, animals in laboratories are deprived of everything that is natural and important to them—they are confined to barren cages, socially isolated, and psychologically traumatized. The thinking, feeling animals who are used in experiments are treated like nothing more than disposable laboratory equipment.

World Day For Laboratory Animals (also known as World Lab Animal Day) is observed each year on the 24th of April, and the surrounding week is known as "World Week for Animals In Laboratories (WWAIL)".
The Day was established in 1979 and has since been a catalyst for the anti vivisection movement to raise awareness of the suffering of animals in laboratories and advocate for their replacement with advanced scientific non-animal techniques.
