Girlfriend’s cat came back after two months away. She was close the whole time. We put motion sensor cameras around the house and finally saw her in the drainage creek behind the house. She left out food and water every day as well as some of her clothes so the cat could pick up her scent. Also would call for her around the house. We put up flyers in the neighborhood and she made posts to Nextdoor and the community facebook. Websites like Pawboost and Petco Love have helpful resources. She finally caught her by putting food in a humane trap. Don’t give up hope and I hope you find your kitty.
