Here in Florida, I believe there are far more cats than geriatrics and Canadians.
A couple of years ago, we had several around the house who liked to spray the door mats and kill the birds and such so I began the N.F.E.P. (Neighborhood Feline Eradication Program) here in my neighborhood. So far we have one member (me)and I have accounted for about ten felines.
Technique in a crowded area requires the utmost attention that even the most staunch of predator hunters would appreciate.
1. One must first evaluate when all of the neighbors are at work so that loud noises are not noticed as much.
2. One must then identify which cats belong to the neighbors (mind you, they go too but you have to be responsible and remember when you remove the neighbors cat for a cover story later).
3. One must determine the best method for removal that will result in maximum performance and the least amount of attention.
The wife found out about the first three that were eradicated through the use of .22 shorts and she was not amused. She insisted I purchase a Hav-A-Heart human catch and release trap. So I did.
But then the problem arose as to where I was going to release them. I mean, if I took them to another neighborhood and released them, it would be like dumping trash on someone's front lawn and that is not nice.
So, after much thought, I trapped the next one live and then shot it in the trap. I mean, although the wife did not find any humor in that either, she had to admit it was more humane than letting them run off and die under someone's house wounded. Women...
Anyway, to try to bring a long story to an end, I have rid the area of feral felines and nobody is the wiser. Also, for disposal purposes, I have found that if you bag them in a couple of bags and dump them in one of the neighbors garbage cans for pickup, it would help to remove your name from the a$$hole list if it is found by the garbage men.
