No experience with the specific product you are asking about, but NRS hypalon has been Bomb proof from what I've worked with. My '95 E-140 is still going strong after about 10 or so years of commercial use on the Ark, and then the rest being heavy private use by me. I have really been kind of a terrible owner to my boat.
In 9 years of commercially running NRS, I have seen 1 blem, it developed this weird de-lam, and so we sold it cheap to a private boater, saw that thing at the put 6-8 years latter, it looked like hell, but he was still running it down the Gorge, and really happy with it( guess he did not care about looks).
I would expect a cat to wear a little faster, since they usually don't have the extra layers of rubber, but if it seems like a sound boat, I would probably go with it.
Do make sure not to over pressurize the inner chamber, I know an owner that had somebody do that to his NRS cat near the start of a Grand trip, exploded the shit out of the guy's boat! Limpt it to camp on ducky's, used every scrap of Hypalon on the trip to patch her up, I believe the tubes made the rest of the trip.
Hope that's somewhat useful, enjoy your new small cat, they are funner than shit!!!
We can't always agree, but we can still be civil to each other.
