To move a foster animal to a new foster parent, first start at the current foster parent's record on the Animals tab. 

Find the correct animal in their animal list, click the green "Select" button on the right side of the row, and select "Return Foster".

After clicking "Complete Foster Return", you'll see a short foster return form to complete. The "Intake into" field dictates whether the animal will be returned to the shelter or go to a new foster parent. If you select "Foster", an additional field will display where you can enter the new foster parent's name. 

NOTE: The only names that will be returned in the Foster Parent field will be those that have been marked as "willing foster" or "foster (active)" on their records.
