We have always had live trees. We don't use tinsel or leave any danglies on low-hanging branches. Most years, we have had model trains which circle under the tree.
The only time Quasar ever tried to climb the tree was 3 years ago. My mum was visiting and put a cat teaser up into the tree on Christmas eve. Christmas morning, the tree was slightly tilted. I found out why when mum told us to look into the tree for "something for Quasar".
There have certainly been problems with tree-climbing Bengals, and I'm sure you will get some of those responses. The pictures I see are always artificial trees, however. I wonder if the prickliness of the trunk and denseness of the limbs of a real tree are deterrents.
Good luck! You'll have to post some pictures.
