Sorry, some more information about the Petsmart event:
 
I've been told you will need to contact Anita Garcia (of Petsmart
Charities, Inc.) for some paperwork, or e-mail me for it.  The corporate
office needs to approve this, and then you can apply to your local store
if they have room.  Also, the shelter has to have a 501c or have applied
for it.  There may not be time to get this all done for this weekend, but
there are multiple events each year.
