16. They can climb trees. Partly for the same reasons, as needing to find high perches, cats like to climb trees. The tree provides a refuge from larger dangerous predators and also conceals prey such as wild birds, which cats can hunt.

So praise kitty for her efforts and wrap the gross thing up in a paper towel or bathroom tissue and throw it away.
