This was the only mention on that site I found of resistance to cat chewing.

This warranty excludes damage resulting from pets. Although "most" cats, like Baxter, will choose to leave these cables alone because they do not like the paracord texture, not all cats are the same, and some will chew on these.
Please take adequate precautions around persistent chewers before leaving them within reach.


I wonder if a paracable like braided sheath could be sourced that would slide over existing cables? wink
