I'm not aware of any Cat shaman fluff.
A GM could reasonably decide it means low powered attacks are fine. I think it's much more interesting to examine the idea of toying with prey, though. Toying is basically entertaining yourself with "how do you respond if I do this?" I see it as maybe gluing an opponent in place, or catching them in a pleasure illusion, a creative use of Influence or another control manipulation, or even non-magical choices. But I would expect a cat shaman to resort to something other than combat first.
