Appendix A:

Category B-E annual hamster use by company. Note that the numbers reported for Zoetis LLC and Zoetis Inc. are combined into one table. All other companies/organizations listed in Tables 1 and 2 have separate tables below of the number of hamsters used in each category. In the final table below, titled “All Categories of Hamster Use Reported Annually for All Companies,” Category B hamsters (those being held for future use) are not included in the “Total Category E” and “Total Overall” columns (the overall column includes Category C – E); those totals correspond to the numbers reported in Tables 1 (overall) and 2 (Category E).
