Spay/Neuter Fund for Farm Cats

We bought a house! Exciting, right? It came with 15 cats (and counting). Which leads to a different kind of excitement. They are cute but this needs to stop! We are partnering up with Farm Feral & Stray to spay/neuter them. For $65 each they will spay/neuter, give a physical, and rabies shot to each cat.  They are ran by donation and are located in Polk County.  (feel free to research)  We are feeding the kittens, as they do not yet hunt -there are 11! This goal total is strictly to spay or neuter. This does not include food or supplement milk. Please help us! We would SO greatly appreciate the help! We would also like to rehome them. Let me know if you're interested! Thank you everyone!
