Bryan's advice is spot on. I definitely agree with his advice to stand hunt over one of the kills, if it looks like he's not done feeding (he should cover it with brush if he intends to come back).
I have one point to build on. In my experience, the type of distress call you use is not very important, unless you think the cat is wise to a call. Predators who have little experience being called by hunters will come investigate any chance at a free meal.
As an example, this past summer I was leaving for work early one morning, and as I headed down the long gravel driveway (it's almost 3/4 mile long - I live in the boonies), I saw a 'yote cross the drive about 100 yds ahead of me. I stopped the car, grabbed my handgun, and stepped out of the car.
Having no call with me, I made a sound that was supposed to imitate a rabbit distress call with just my hands and mouth, but sounded more like a guy trying poorly to imitate a dying rabbit

He immediately stopped and then ambled into the brush next to the drive. I kept calling, watching for signs of him, but didn't see any.
As I was about to give up, I turned my head, and he was sitting just 20 yds behind me (he had circled around me) with his head sideways, like a dog does when you make a funny sound. It took everything I had in my not to burst out laughing. I turned slowly to try taking a shot at him, but my motion spooked him, and he disappeared, never to be seen again.
The point is, if I can call him in with that poor excuse for a call, I don't really think the call one chooses is terribly important. Being at the top of the food chain (again, this only applies if they aren't wise to humans calling them), they will investigate any sounds that even remotely sound like a free lunch.
Good luck hunting that cat, and don't forget to take and post pics if you're successful!

Scott
