I have steel in the ground year around and I have had the opportunity to use and test every trap on the market and as far as coyotes goes and a good coyote trap is a good bobcat trap, the best trap on the market is the #3 Bridger with the Canadian modifications. Unparalled holding power, has power enough to power through moderate frozen dirt, wide jaw spread, animal comfort with the wide double laminated jaws, heavy duty center base plate, off set lugs. The dogs will get bent on some coyotes but you can replace them with a laminated dog and never have to replace them again. If trapping cats only this is somehing you don't have to worry about as cats don't fight a trap like some coyotes do.
