My humans are not always happy when I go round the living room, rubbing my chin against the door frame, the chair leg and various other places. I also rub against any new item placed in the room.
What they dislike - if they notice it - is a tiny smear in the places which I have rubbed repeatedly. Sometimes they clear it up using water and soap.
That absolutely ruins all my hard work. And it's very stressful for me.
I am rubbing my cheek against the furniture and walls in order to mark this place as my safe home. It's important to me that I do this. It's like a post-it note to myself, reassuring me that all is well and I can relax.
Each time some interfering human wipes it off, I have to put it back on. And I have to keep it topped up with frequent cheek rubs, so that the whole place smells RIGHT to me.
Take your horrible human hands off my skirting boards!
