Can you imagine shopping for a cage that you intend to put a person in?
You would have to constantly watch what you were saying – scanning the sentences ahead to avoid anything that might give your plan away:
“Excuse me, I’m looking for a dog cage – oh about the size of a 38-year-old white female… dog.”
Or perhaps.
“Can the metal on the door be electrified so as to prevent it from being opened from the inside by the… dog?”
Or is this just me?
