Baiting cats is not that effective. They are not the gluttons bear are. Better to wait for fresh snow and get on fresh tracks. Or just spend lots of time int he woods and you may just see one of the cats that see you.
Baiting does work, that's how I took mine. Works better later when the temperatures stay down, keeps the meat from turning too quick. Dairy farmers pay about 15.00 to have stillborn calves hauled away, usually glad to have them taken. Should be some in your neighborhood. I don't take too much stock in the belief that they only eat their own kill. Worked for me, and I know a few others successful the same way.
Yes calling works very well.
