A few large snares (3/32 inch cable) are suitable for bobcat or beaver and will be strong enough to handle medium-sized game. About a dozen small snares (1/16 inch cable) will be ideal for squirrel, rabbit, and the like. A 4 foot length is fine for all of them. A dozen snares is the minimum I will pack in a kit, because it’s the minimum I will set. Always remember that trapping is a numbers game. Unless it’s virgin territory teeming with game, you’d be lucky to catch something in one out of ten traps, every couple of days.
