Tell your son hes probably hooked for life.HE seems to be doing great!I started when i was 8 im 66 now and every trap check day is still like christmas morning!! Is he putting up his own fur or selling on the carcass?A good cat in my area runs 400to800 dollars depending on the belly width and the spots.Of corse every body is trying to trap them or steal them from you.Remember the best teachers are the animals themselves. but it doesnt hurt to have an old trapper around to pick their brain .good luck!!!
