The cactus cat is a lesser known mythical creature from the pioneering days of the american south west with lumber jacks credited with spreading the stories.
Personally I am not certain about the lumber jacks having much to do with with the myth. I mean lumber and cactus are not something that comes to mind as being near each other...but I could very well be wrong.
The Red Ash Cactus Cat is pulled from the myth and brought to RPG live in the Red Ash System. Not only are these predators dangerous to Small Sized creatures (and smaller), but they are somewhat humorous too. Getting drunk off of fermented cacti juice and carousing all night, reminds me of a few misadventures from a while back.
Anyways you can read more about them here.
All the Best,
