Aside from the obvious----the cat....

As a foster parent I KNOW that foster parents would LOVE to have donated
formula. You might check with your local DHHS to see if there is a
foster parent organization that could be  a clearing house for you.
Also, shelters for women and children would probably have a use for it.
