anyone ever used feral cats on their property?

i was talking to a lady at work and told her we sometimes have some snakes and mice around the cabin and she said I should consider getting a couple of rescue feral cats. she said the rescue feral cats are "fixed" and could easily survive on their own with me being out there mainly just on weekends. she says they could drink from the pond and would only need some food at first or I could put some food out on weekends when I'm there. i guess they could find shelter in an open end barn I have near the cabin.

any thoughts on this?
