I have been completing Aela's quests having completed the main Companion questline in order to obtain the Totems of Hircine.
She gave me the Animal Extermination task of clearing Greenspring Hollow in Whiterun of a Sabre Cat, which I had already done for her earlier. When I arrived the previously defeated Sabre Cat was there. What I ended up doing next was casting Raise Zombie on it before it died and turned to ash. Now everytime I return (it's been over 30 in-game days now, I just used wait in Breezehome) the pile of ash remains and the quest pointer points to it as if I should defeat this.
My question is will the Sabre Cat ever respawn so I can complete the quest?
I'm playing on a PS3, so unfortunately cannot use mods to fix this.
