Anonymously, what a cool place!
Weezer, are you hoping to make them indoor cats, outdoor cats, or both? A few of my current house cats are former outdoor strays, and they’re indoors strictly except for a smallish outdoor cat enclosure they have access to 24 hours a day. This has been a tremendous help to cure that wander-lust. Do all the cats get along, and are they able to be handled by humans at all?
My rule of thumb when bringing a new cat home is confinement for a few days, in a small, quiet room (a guest bathroom or spare bedroom works well) so they can adjust to their new surroundings and hopefully the homing instinct to their previous dwelling will at least lessen. Free roam of a new house, the entire thing, can be “too big”. One of my newer cats was kept in a covered ex-pen, and if she gets afraid or tired she seeks that place out as “home”. I haven’t had the heart to take the ex-pen down as she loves it 🙂
If you’re planning to keep them outdoors, a barn or an outdoor building that has plenty of air flow and is cool would be your best bet; if you’re able to keep them confined in it for a few days. Feed them there, let them know that’s where food arrives, and that it arrives at the same time every day so even if they do tend to roam around, they’ll hopefully come back at feeding time.
