zdwDesk for people who work at home with a cat
The problem is that cats can flawlessly detect when something was made for them to use, and then will not deign to use it.
Meanwhile, the cardboard box you have forgotten to take to the recycling for three weeks will become their palace.
I just put an appropriately-sized cardboard box on the corner of my desk.
Ditto, a short box from wet cat food worked really well to keep my cats off the laptop.
I have a USB keyboard and external monitors, so the laptop sits off to the side, and is warm, so they loved to sleep there. Particularly a problem since it also has a button that powers off the laptop. I made a keyboard cover, but even then it was problematic with them sleeping on it (thermal throttling).
Putting a box on the desk solved that, they prefer it, until a second cat wants to join the party, which is thankfully rare.
