Those vertical blinds make a clacking noise when kitties look through them. It’s a distraction but I don’t admonish them for being on the desk until I hear something fall off and land on the floor behind it.
My grandfather on my mother’s side made that desk and chair for me when he was about the age I am now. He was a carpenter and a wanna-be cabinet maker. He and my dad replaced the original laminate desktop with a solid walnut one while I was away in Viet Nam. It has more sentimental than actual value.
