Animals Used for Experimentation: 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. STILL NO MODELS TO SUBTITUTE ANIMALS BEFORE TESTING ON HUMAN.
