Put your cat in the box.
As you can tell, instant cat heaven! Any given time I look into this box, there is a different cat in it. It is their very own personal sanctuary and I, I have a box in my dining room. (eyes rolling)
Yes, I know. We can buy a cat thingamabob or two that won’t be as nearly as unsightly as a cardboard box, but we’ve tried all those things. They are just NOT interested, won’t even look at it. It is beneath them. But a box!, an average, every day, jo-blow cardboard box with a hole cut in it - TREASURE!
