Pineberry Feral Felines Spay and Neuter

Is a community of friendly feral cats that I am trying to raise funds to get them spayed and neutered. I am the home owner that these kitty's have adopted to call home. We started with our own 10 cats 6 years ago, some inside pets and some outside pets. It seems people like to drop unwanted cats in my area and they seem to find there way to my home. I am up to 70 that come to eat at my home. I have become friend with most. I give the health care as best I can when they are sick. But I need to start getting them spay and neuter so their numbers stop growing.
