Our little cat keeps disappearing. She is 2 years old and neutered. since this summer has lead a normal life. Coming in and out when she wants. Occasiinally staying out at night but usually back in the morning. She is a loving litte girl. Anyway in July she went missing for a week. Looked everwhere for her. Then she jyst reappeared. In August she went missing again, this time 3 weeks. Almist given up hope then again she just reappeared like nothing had happened. a bit hungry but not starving and very loving to us. So today she came back after being missing for a week. Same as before just srrived, stuffed her face and took to the sofa. We have no idea where she goes, neighbours do not see her. Any ideas what to do
