We have mountain lions and jaguars here at MTCF. I did some research years ago also on the mountain lion in North America. The highest mortality levels of mountain lions for example are adolescent males once they leave their mothers and start to wander far to look for their own territories. And the leading cause of death was being killed by other males in established territories. The 2nd leading cause of death was getting hit by cars. These conclusions came from data gathered from radio collared males.
With native habitat severely reduced encounters with rival males has probably increased, so yes, reducing populations to "parks" has aggravated these cat to cat killings. But before habitat destruction this probably was the leading cause of death to adolescent males. Historically a wandering male mountain lion had the chance to establish teritorries that encompassed low land valleys, wetlands, foot hills, prairies and mountains. Think about that diversity and abundance. Today many of these cats have to eak out a living in a teritorry much restricted. This has caused more antagonistic intra-specific encounters no doubt.
Jupiter, your partially correct .... but these cat to cat killings are part of the ecology of many cat species.
