There are many ways to view the animals per cage in the mice list (sort and filter for strain and sex, group by cage)

For performing the work, we recommend the Cage Rack View: 

1.    Go to Cage and select Room and Rack, and filtering as needed by strain can help you quickly view numbers per cage and select to combine. 

2.     4, 3, 2, and 1 Mice per Cage

3.    View number and sex in cages in Staging Area

4.    Move those cages to the workbench

5.    Move animals together as you did physically (using drag and drop) 

6.    Delete empty cage
