You mind sharing about your sets? Whatever set you’re using is darn sure effective
What I do won't work for everybody. But this is the deal: I have a lot of beaver carcasses; so I take them up in the woods and leave then in places that look "catty". One carcass per spot. No traps. Then after 3-5 days I come back and check the carcasses for activity. Cats will feed on a carcass for 3-4 days until it's gone. In the interim they cover the carcass so that's how I know it's a cat and not a gray fox. possum, etc.
SO now I set up the carcass best I can and i can pretty much figure that two checks will get all the cats I'm going to get. This method cuts down on travel expenses as three to four trips and the job is done.
On this recent adventure I put in 900 miles to get ten cats and four civets.
Normally I only get one cat per more or less 5-7 carcasses. But I had phenomenal success with this last batch...10 cats for 23 carcasses!
I will add it's always a question how many days to wait before inspecting carcasses. The longer the time lapse more chance it gets discovered. But if the carcass gets discovered the first night and I wait four nights it might have finished the carcass and moved on. Sometimes I find that a carcass gets hit after I've done my 4-5 day gig so I miss that one too. I often go back and look at failed spots to see what eventually happened. If a cat got it I will see the spots where it covered the carcass.
I often will set up the spot with another carcass (same year or subsequent year) and these end up being higher percentage locations.
