That’s what I’m hoping for... a good deal like that. And they’re perfectly welcome to stick around and become barn cats or couch cats if they want.
I think if you contact them, or the animal shelter, they can give you the information. Don’t tell them they are not going to remain feral or they will figure they have you hooked :) Just that you have three feral cats hanging around, if you trap them, who can spay/nueter and do they provide funds/voucher.
