X-23 only has metal in her claws, not her bones, so it's a moot point ;)
The fight you're referring to was Wolverine vs. Mr. X. Mr. X was only a telepath, who used his powers to get an inside track against his enemies. His combat ability without relying on his powers was fairly lacking, hence Wolverine's ability to maul him.
Cass' skills are different. They're not straight fighting style recognition, so much as expert knowledge of body langauge. She can see he punch or attack coming in your stance, recognize the pattern that you're using to fight, and counter it.
Being feral wouldn't help much, in that regard. It might make one's style unpredictable yes, but would likely telegraph their body langauge a mile away.
