Most cats are stupid compared to coyotes. With that said though, their movement's make them difficult to catch at times as by the time they do decide to wander around where your traps are it's a sure bet a coon, possum or other undesirable will already be sitting in the trap watching them as they walk on by, lol.
They won't work a set hard, usually just walk up take a few sniffs then walk on off. Sometimes they will just walk right on by and not even stop.
Cats don't like to back up either so sets for them should have a entrance AND a exit away from the set, let them walk THROUGH the set rather than UP to the set.
Blind sets in trails they are using are my favorites if you can find any. Two traps placed in the trail are good insurance on not missing one, i also like drags at these sets so the animal can get away and not destroy the set area, plus using two traps once one makes a catch and drags it off you still have another trap waiting on the next cat/fox/coyote to come along.
It's hard to be an outlaw when your not wanted anymore.
