Mr Smith calls our pets "groupies," because they all follow me whereever I go...and leap up to run ahead of me when I move. As I am now used to this, it works fairly well...until the cats try it when the lights are out.

My dogs do this.....always follow me. I can't even go to the bathroom. My ancient poodle, the one I thought was on death's door last month - and who now is doing great - is the worst. It's a traumatic event when I'm out of his sight.
And yes, I stumble over them. I have to stay aware. I'm sure I will end up with a broken hip, end up in a nursing home, die, and my death certificate will read "Cause of death: Dog/gravity".
