It's probably because it smells familiar to them and the new one still has a new scent to it. I'm sure once it's there for awhile and they each check it out, it will become more and more familiar and they'll start liking it just like the old one.

*I* can't believe that with 13 cats you've only now gotten around to getting a 2nd tree!
