Rehoming our cat (Portland)

Have to rehome our barn cat as someone is targeting her and I can’t figure out who. I would’ve kept her inside but my family is allergic to cats. Want her to find a home who will keep her inside only. (She will be stressed for a while as she’s been an outside cat.) She is spayed and a very loving cat. Would be great in an elderly home. Only downside is she needs a home without other cats or dogs and especially no small critters. They just stress her out no matter what. There is a small rehoming fee to make sure she doesn’t go into the wrong hands. *text only
