When a predator attacks it often claws onto the back-end of the mammal and brings it down. Thus the claws on the hind end would be advantageous in fending off a cat-like predator. Also when a hose mates, it doesn't lay on the other's back, it places his fore-hooves onto the female's back.
So, stop pulling "science" out of your ass, would you kindly

Yes, I often think of porcupines when I think of scary. I don't really define any of these animals as cute, tigers are majestic as fuck, not cute.
Also these are aliens where the humanoids are orcs
