Maybe they can only wear 7-leagues boots ?
More seriously, I can't see why their fur should give them AR. I am not used to kick kittens, but I am positive their fur won't protect it from my attack... I think that their fur should give them bonuses to resist cold, that they should have nightvision and maybe enhanced reflexes giving them better initiative.
On the stats side, they may have lighter bones, giving them less strength. Cats are long runner so maybe they should have less constitution. Finally, I think cats are not prone to lasting actions, so maybe a low self-discipline ? To compensate this, I woud propose higher dexterity and speed.
Maybe something like :
Dex +3, Speed +2, Con -2, Str -2, SD-1.
Cold resistance +4
Nightvision greater
Enhanced reflexes (initiative +2)
