I think this report is worded in such a way that it might be somewhat misleading. It states that the researchers found the contents of the lions' stomachs contained "cats, dogs, and other domesticated animals." "Other domesticated animals" would include sheep, goats, chickens, calves---all sorts of farm animals. It would be interesting to see how many lions had eaten dogs and cats and remove "other domesticated animals" from the mix for that one statistic.
I also bet that most of those lions killed under depredation permits had been working farms and ranches.
