Rachael and Monica have moved into a shared house with several other occupants. Monica doesn’t like their new accommodation though because of the angry and aggressive cat that greeted them when they first walked in. Rachael realizes that there isn’t really a problem. Why?
There is a mirror near the entrance. Monica is a cat, saw her reflection, and thought that it was another cat challenging her for territory. Rachael can cover up the mirror until Monica becomes settled, but Monica will figure it out eventually even if Rachael does nothing.
