The injustice of excluding laboratory rats, mice, and birds from the Animal Welfare Act.

A major shortcoming of the Animal Welfare Act is its exclusion of the species most-used in experimentation -- rats, mice, and birds. Considerations of justice dictate that extension of the law to these three species is the morally right thing to do. A brief history of how these species came to be excluded from the laws protecting laboratory animals is also provided, as well as discussion of the implications and significance of expanding the law.
