Fox and yotes are almost the same if ppl are using the bunny in distress call in ur area quite frequently go to the cat distress or i like to use the fawn distress during or after deer hunting. varmints get smart if you use the same call in the area just set up with light or no wind to your face and watch behind you. most of the time them critters will sneak behind u and busted without a shot so if you can get a spot where you can see behind u thats the best. hunt the edges like u saidbecause in the middle of a woods they can come anywhere until they hit ur tracks then their gone. i personally like the cat because they are not as familiar with hunters using them unlike the rabbit where every hunter in the county uses them. mix things up too, call for 2 min, wait 1 min call 4 min wait 2 call 8 min wait for 30 min then go to like the woodpecker distress or something like that good luck
