As you can see by the proximity of the caster of my office chair to Maggie and Banjo as they catch some rays, I must be very cautious about getting up from the desk. There's no simply pushing back then standing up around here. Nope. We have to pivot, examine the immediate area for dogs or cats (and any wildlife that may have wandered in), shoo or forcibly remove any nearby critters, and then you can push away from the desk.
