Two additional hypotheses:
- They were larger than necessary because they were "one size fits all". You'd pad them internally with some socks, as needed.
- The shoes survived because they were too large for most people. For example, other shoes could've been used by the soldiers, or simply stolen by outsiders once the fort fell into disuse.
Kika: raise the palm of my hand threateningly, and start saying things like "nojenta" (disgusting), "jaguara" (sly), "cachaceira" (drunkard), "chata" (boring) etc. Most cats will go away. Kika will however come closer and turn her butt towards me, as if saying "slap it".
Siegfrieda: start speaking in German. No, seriously. She actually identifies when I'm speaking in Portuguese or in German, and if it's the later she immediately thinks it's something with her. Good luck finding 99 cats with a bent mouth and a protruding fang, though.
