I have yet to find any evidence that either of my cats has jumped on my workbench. The older one is likely too fat to jump that high anyway, but the small white one I've found wedge on my other desk behind my monitors. Will be interesting when I get started on my model railroad, on my old one, I used to find evidence of Godzilla-Cat intrusion, mostly in the form of paw prints and claw marks on the extruded foam insulation I used as the base. Did lose a part from a model once, found it on the other side of the front door - seems she absconded with said part and was batting it around and it went under the door, out of reach.
I have yet to put hooks on the ends of my shelves to hang test leads - and I'm kind of thinking that's probably a good thing that I keep them in a drawer under the bench.
The dogs don't have a prayer of jumping up to the bench level. They need stairs to get on the bed. Pugs are much in the jumping department.
