I think that all cat's are considered a feral animal that are outdoor's wheather someone own's them or not. If they are outdoor's then you cannot contain them as they will jump over thier fences to get out of the yard's.FYI, I had a round with the feral cats up here. If it's not pettable/adoptable, they won't take it. If it's a neighbor's owned cat, you might be OK, I think they only take them by appointments though. Funny I think they still come out to pick up dogs....
