Ok, well, the little problem is that I can't move any of my pets to different groups. Also, there is no little box there that you usually click to be able to move them. Help?
Check that you are logged in to your account (if you are logged in, there should be a "logout" link with your username next to it at the top of the page).
If you are logged in to the account that the pets belong to, the tickboxes and stuff should appear. Are you sure that it shows you as logged on on the "my pets" page?
