You can check the BS01 article on the Rahi, but it does state that, “The Kavinika’s defenses are its sharp teeth and claws. With its claws, the Kavinika can climb buildings to hide.”
I will agree that visually, it doesn’t seem likely, but that’s how they’re described. And yes, they have been mutated by the Visorak’s venom, so some added differences physically as well.
As for how to defeat the wolves, I’ll leave that up for the rest of you to find out.
