1. This is the main page, with the top level menu, clicking one of these menu items will load HTML using ajax.
2. This is the menu which is loaded next,the buttons along the top switch category which will also load new html below. Clicking on one of the images should then load more HTML which will be what animals are available for sale with some information (XML?)
Oh, and the end user should be able to login as an admin and customize or even add new animal categorize ect...
