To get them I used to just go to the dairy and tell him I needed some and he would live trap them for me. Now I just go to the vets office and ask for kittens they have that were dropped off.
Kell, you do realize that you'll be "marked for death" by the hordes of cat loving extremists, don't you?
There is a group that advertises on the our local radio, dedicated to spaying and neutering feral cats and releasing them to live happy little kitten free feral kitty cat lives. If they or others find out about this, they would declare jihad!
Personally, I find the best method to calm that "exuberant Tom" is to stick their head in a boot!
