Somewhere there is a sunny house and a yard with trees and plants. inside the yard exist an animal the most people know it as cat (I m not sure if it is cat ,what I know for sure is that it has lives more than One). She lives free and although someone feed it regularly she hunts other animals like mices,birds etc. she can climb ,hide and jumb in order to catch her victim.
The birds make nests in the branches and the tree protect them from the monster that is messing around inside the yard.
I don't know what will happen ...make your own end or do it yourself
