The application that is online is for those in the military who need their pet fostered. Those who want to volunteer to foster have a link to send an e-mail to the program.

I went searching around the pages that have to do with the military foster program and found a link specific for those who need a cat fostered:

The Feline Rescue Network

I also found contact information, that included a phone number for NetPets here:
NetPets Contact Information

And this message on that page:
NOTICE: UPDATED (3/23/02)
Please pardon any delays in our responding. Right now all of our time is being devoted to the NetPets.Org's MilitaryPetsFOSTER Project. At this time we are responding to all emails on a priority basis only.
It was dated last March. I am planning on calling the phone number in the above link Monday after I get home from my morning van run so that I can ask them if the program is still active. I have a son and a cousin who are both active duty and people in the military have been very busy since 9-11...so I am still suspecting that NetPets may possibly be getting overwhelmed with requests for help.

I'll let you know if I make contact via phone tomorrow.
