We recently added a second cat to our home, and she does not tolerate the other cat. We don't want to get rid of either cat, so we found a way to permanetly separate them. This has worked well, except tfor he sliding glass door in the living room. I was thinking about a privacy window film for the lower half of the glass door, which would be decorative, and still prevent the one cat from seeing the other.
Before I go this route, I was wondering if anyone had another idea of how to block their view...maybe something cheaper or simplier.
