Sometimes when I'm lying on the couch, Charlotte (pictured below) will climb up on my chest purring up a storm and just plop down on her side to signal that she wants an hour or two of belly rubs 😄🥰
Most of my cats don't seem to have a strong opinion of belly rubs half the time. They just kind of look at me like "hey do you mind not doing that?" and then walking away or just letting it happen.
