As American who support Serbia over Kosovo I knew that, I found out that they also saved American pilots, during the WW2 the Guerrilla Cetniks led by Draza Mihajlovic saved American pilots who crashed in Yugoslavia or were shot down by the Axis powers (Italian Fascists, Nazi Germany, SS divisions of Croat Ustase, Albanian SS Skanderbeg, and Muslim SS Hadzar)

Had the same problem. Two from the same litter - lived quite peacefully together, until one escaped. It was recaptured the next day, but in this time the two forgot that they knew each other, and they fought until one was killed.

To be fair, I was told that this might happen if they were separated for any length of time, but had thought that they'd cope with a period under twenty-four hours. Were yours ever separated?
