Possums don't like pears

For the first time, our little orchard has borne fruit. We have two small, espaliered pear trees (one Williams pear, one Josephine), both laden with fruit. They are definitely  not the perfect supermarket variety, more the lumpy and bumpy organic variety, and I am so looking forward to trying them! I have picked a few but they are still very hard and need to ripen. No apples, but happily, our little trees were not attacked by possums this year. Two of my apple trees died last winter and I had to pull them out, the others are all stunted after two years of having all their leaves eaten by possums. The pears were spared. It seems possums don't like pear tree leaves.
