Animals endure inhumane treatment in the way they are collected, transported, handled, raised, and killed for dissection.
Millions of animals are bred and killed every year for dissection. Others are captured in the wild. A number of investigations have documented the treatment animals receive before they are dissected.
When animals are not bred or caught for dissection, their bodies or body parts arrive in classrooms from the equally cruel meat and fur industries. Fetal pigs and organs from cows and pigs are obtained from slaughterhouses. Many students are rightly concerned about the welfare of animals in current farm operations, where animals are crowded together in filthy conditions, often unable to move naturally or see daylight.
Pigs are sometimes stunned incorrectly and put into boiling water (meant to remove hair and soften skin) while still alive. Many have their teeth broken off by pliers and their tails severed with no anesthesia. Pigs experience such high levels of anxiety awaiting slaughter that many develop a hypermetabolic stress syndrome, where their bodies overheat and heart failure can occur.
Cows are also often improperly stunned and are still fully conscious as the slaughter process begins. Many are burned or castrated, or have their horns torn off—all without any form of anesthesia.
