I never did measurements, just like I rarely do in cooking, but I know what I have used. House cat is one of the best ingredients, although I wouldn't suggest you shoot your neighbor's pet (unless you know they are gone to town for a while). I know around here it's a common occurrence for cats to get killed in the road, so that's a good way to obtain one. House cat gives off great odor, even when frozen solid. Cut up the cat with a hatchet, hair and all. Do the same thing with a groundhog and add it to the mix. Add just about any fish you catch to the mix, but in much smaller amounts. I never used rabbit, but for no good reason, it's just how I made it, and it worked well. I'm sure there are better bait recipes that people on this forum use.
