Good morning Dan,
Have I ever seen "tree ratz" attacking mangos? Bushytaileous treerateous (an appropriate binomial nomenclature) raid everything. They eat a holes in mangos, bananas, and anything available! The more Yellow and Red Ratsnakes around, the better. Especially large Yellow Ratsnakes, they do a good job on these bushy tailed tree rats. Yellow Ratsnakes are more effective than cats.
One thing about them is that they know better than humans when fruit is ripe. Another reason to harvest mangos, bananas, and avocados "mature green." I greatly dislike bushy-tailed tree rats.
