All of the branch cat dens have entrances to the main chamber of the thicket and an exit at the back. These entrances provide the feral cats with safety.
I was still curious and I attempted to put my head in the passage opening to get a better look at the leaf bedding area, I wanted to know if the cats laid on top of the leaves or if they dug a den into the earth.
No sooner then I put my head into the small opening I discovered that I was not alone. My presence in the thicket entrance was not appreciated as a feral cat from an upper passage snarled at me and it was enough for me to back out of the thicket. My findings were conclusive and I was was confident that the feral cats winter thicket den would provide them with a wind block and warmth from the leaves.
When snow is too deep we will clear a path so the cats can come out of the thicket and go to the feeding station.
