you sound like me lol.. man wish you were here catching cats to spay and neuter. Alot of males spraying over here.
Contact cat rescue groups. See if they will help pay for the spay/neuter if you release them and feed them after its done. That's what I have going over here. But this is a volunteer rescue, made up of cat lovers, I had never heard of it before they showed up down here asking for our help to control the cat population. It was kinda strange, they are on the opposite side of town from us, about an hour away. But I am not saying no. Because of them I have gotten my 7 female cats spayed, 3 tomcats I caught neutered, and found a home for a special needs kitty Mittens. Mittens was thrown out of a moving truck right in front of me, she had broken teeth, no hair on the back of her legs, and was full of fleas. For a year I kept her and did my best for her, got her looking decent. Then she started losing teeth and I didn't know what to do. She lived outside due to her fear of my dogs. I contacted the cat rescue and they came and found her a home with 8/9 other cats, no dogs. She gets special soft foods because of her teeth and is spoiled rotten. Anyway, see if you can find a cat rescue group, they really do care and try to help.
