I heard the horror stories of people going 2 or 3 hours opening cats at lvl 19 to find either nothing or a lvl 20 cat, so i came prepared, had a large slurpee in hand, bag of dorito's on my side and enough time to search for my kitty. I get to the ruins, open a cat and it happens to be a level 19 ghost saber. All that preparation for the easiest tame i've ever done.
