So far it looks very good. For some reason under firefox I get 2 donate buttons.
Have you considered click here for hosting needs. This will remove the need to mask the domain name allowing users to send the links to friends.
The only other issue I can see is that you might want to consider a default template for the re-homing page as it will make it look more professional. Similarly I would consider a vital stats on the For Adoption page and then link to a separate page so people can view photos in more detail and allow people to send to a friend, either by a link option or opening the users mail client.
Final note how about a successfully re-homed page and success stories pages?
