At the moment we are going through a very stressful health issue with my husband. One of my cats, Lily has always been attuned to my stress level - becoming a Velcro cat in times like this. She is the oldest in the house (171/2). The youngest is Sterling just 2. In the morning we seem to have developed a ritual. As I come down stairs Lily is on my left and Sterling is on my right - never the other way. They are usually on the same step as I am too. If I stop, they stop. If I get side tracked upstairs doing something they wait for me at the top of the stairs, even though their breakfast is down. waiting for them. I guess it is silly, but I think it is cute they do this.
