It Is A Mistake To Assume That

No Consideration At All Is Given To The Interests Of The "pests" - The Very Word "pest" Seems To Exclude Any Concern For The Animals Themselves. But The Classification "pest" Is Our Own, And A Rabbit That Is A Pest Is As Capable Of Suffering, And As Deserving Of Consideration, As A White Rabbit Who Is A Beloved Companion Animal.

The Principles Of Ethics Come From Our Own Nature As Social, Reasoning Beings.

There Could Conceivably Be Circumstances In Which An Experiment On An Animal Stands To Reduce Suffering So Much That It Would Be Permissible To Carry It Out Even If It Involved Harm To The Animal... [even If] The Animal Were A Human Being.

People Tend To Care About Dogs Because They Generally Have More Experience With Dogs As Companions; But Other Animals Are As Capable Of Suffering As Dogs Are. Few People Feel Sympathy For Rats. Yet Rats Are Intelligent Animals, And There Can Be No Doubt That Rats Are Capable Of Suffering And Do Suffer From Countless Painful Experiments Performed On Them. If The Army Were To Stop Experiments On Dogs And Switch To Rats Instead, We Should Not Be Any Less Concerned.

For Most Humans, Especially For Those In Modern Urban And Suburban Communities, The Most Direct Form Of Contact With Nonhuman Animals Is At Meal Time: We Eat Them.... The Use And Abuse Of Animals Raised For Food Far Exceeds, In Sheer Numbers Of Animals Affected, Any Other Kind Of Mistreatment.
