I scent mark my home - for reassurance and home-making.

The video shows Shirty Bertie making his rescue pen into a home by rubbing against it. 

A home has to smell right. My core territory has to smell of me (and my scent glands), my human and any other friendly beings that I live with. So I spend time rubbing my chin against the furniture to spread my scent.

My chin also smells of my human, since I have rubbed it against her when I am feeling friendly. Then I pick up the scent of the furniture, itself, and rub her again. It's a careful mix.

This is feline home-making. I need my home, my core territory, to smell safe and happy. So if I feel just a little insecure, or if I have come back from the cattery, I will remake the scent profile.

What I hate is when the home scent is destroyed by painting, or builders, or some kind of alien scent brought home by my human. When Celia came back from hospital, I had to re-rub her and the home, because she brought back medical smells, like the smells of a vet.

• He was called Shirty Bertie because he occasionally nipped his rescuer.
