Category A - NO live animals are contacted - includes purely observational field studies or use of cadavers not euthanized specifically for this study. (a "wildlife" or "tissues only" form may be most appropriate for your project)

Category 1 (reported in column C of the USDA annual report) - No/minimal pain/distress/discomfort is associated with the protocol and no pain relieving drugs or treatments are necessary.

Category 2 (reported in column D of the USDA annual report) - Pain/distress/discomfort is associated with the protocol and appropriate pain relieving drugs or treatments are provided.

Category 3 (reported in column E of the USDA annual report) - Pain/distress/discomfort is associated with the protocol but pain relieving drugs or treatment are withheld because their use would interfere with the study objectives. (This must be explicitly scientifically justified and approved)
