Old school engineer/architects drawing boards were also covered with the same colour green mat for the same reason.

Eqivalent to a mobile billboard, so they should be paying the wearer.

When my cat got old, she couldn’t jump up onto beds and chairs anymore. So I would try to lift her up onto places she used to like.

Cat said no. If she couldn’t get up there by herself, she just didn’t want to go there anymore. Fierce independence.
