The Cat Pages are an ASP application which can be a bit difficult at times - especially when the site is busy.
Usually what happens is that if it takes you more than 20 minutes to complete the whole process (including the pictures upload time - which can take a while) you get a message error.
Like Terri and Donna said, if you don't want to keep trying, you can always send me the pics by email to email@example.com and I'll upload them for you using the administrator interface. Just don't forget to tell me the page number.
Thanks for making a cat page (or at least trying
) - don't worry, we'll get it online in no time.
