I think their tactic would be...silent (you cannot see or hear them, even with high perception).
They would be incredibly fast.
They ALWAYS attack you from behind
And once in battle they try to quickly scratch you with their heavily mutated claws and then they would step back in a defense position. This will repeat until you or the cat is dead.
This cat would be very fun an scary to fight.
Maybe we can assume that the cats use the same stealth technique like you (the Chinese stealth armor)..but they dont wear anything..its in their mutated nature after all.
Seriously? That's like the red dead redemption mountain lion all over again...
Or a Deathclaw. rarely saw those coming in FO3...
I wonder if House brought a cat with him while being cryogenically frozen
(or at least still have it stuck in ice) >_>
and both are bald because of being cryogenically frozen?
