Cat logic:
Empty, fluffy, comfy cat pillow in front of the vent....
Pile of floorboards from kitchen reno, vacuum, plant stand and reciprocating saw in front of the vent. Clearly this is the better and more comfortable option for getting warm.Or perhaps here, where she will absorb the heat full blast and come away smelling burnt, while also sitting on the hard wood floor instead of the comfy cushion.
Sisters. At least the younger one knows what the cushion is for.
What do your pets do that defy logic? Or defy human logic, at least?
