Come on Wampum........get a little creative.
This is all you need.
One cat, on gunny sack. Two pieces of heavy cord about 3 feet long.
Put the cat in the sack. Use the cord to tie the top shut. Find a branch several feet off of the ground. Tie the cords at least a foot apart on the branch.
Then comes the secret part.
Wind 'er up.....tight.
Let'er go and head to your shootinspot. About the time you get there that cat will start yawling. (Its a horrible sound). The thing will wind and unwind for quite awhile. About a normal set time.
The cat seems to be good for only a few of these sessions and the sack gets pretty stinkin' some times. Stinkin' enough that you kind of wanna leave the sack and the cat behind.
If the cat happens to be one of you wife's favorites and you have to bring it back, be very care when turning it loose. It won't have any idea or even care where up is and up yours it may run when released. Do this out side so the wife can't see. It seems wives are a bit sensitive about this kind of thing.
BTW, it really does work.
