(Dust rule in my house - If you touch that shelf and it shows - then get a rag. The cat swished his tail on a shelf once and I used his tail to finish dusting the shelf.)
This is the most creative answer I saw on this thread but I think any of my cats that I used to dust would either scratch or bite me. Even if they are mostly good kitties. LOL.
By the way I almost never dust even though we live in the flight path of B52 bomers and other military planes because my hubby does the dusting. I think that solves that problems. HA.
