Webkinz mutt and domestic cat mystery

Have you ever been in the clubhouse and seen a mutt or domestic cat? I know why-it's from webkinzdemo.com, a website for people in other countries, but it is still a mystery. What I do know is that the dog is automatically named Patches, it's PSF is a burger, and the PSI is the red dragster. There was recently a mypage pet of the day that was a mutt, named Princces that was Member of the day. They had one pet and have been on since June 29th! How's that possible because webkinzdemo accounts only last one day. If you know anything about this, tell me! I will help you design a room of your choice and invite ANYONE WHO HELPED ME to a party in my amusement park room. So please help me with whatever you know that I DIDN'T ALREADY MENTION!
