This set or variations of it works well for me and the flagging scares a lot of the coyotes from the set .
The feathers were snow goose feathers I picked up where something had an easy meal from cripples ( large irrigation lake close) from waterfowl hunters, Chicken Catch aRory was humurous, Your Goose is cooked is another.
I use multiple scents at cat sets and their is castor on the upright for rubbing,gland in the T-bone and Nelson cat-based in the dirthole and yes urine, maybe overkill but sometimes you only get one chance at a wandering Tom.
A friend went on my line as a visitor saw all the feathers, t-bone droppings and exclaimed it looked like an Indian burial mound set.
Most of my sets are walk=thru or modified walk-thru.
Normally I use less feathers but the goose feathers where handy, usally a single feather will suffice as this set shows.
