We adopted a 2 year old Siamese cat one month ago from a rescue org who told us our girl, Gabi, was socialized, sweet, and affectionate. When we met her she was in the back of her crate very shy but we thought she was just scared. We are new cat owners and did not recognize signs of a non socialized cat. Now that we've had her home for a month, she is still hiding all day, does not let us approach her, she does not purr or meow or rub her face or body on anything. She does play sometimes, she is active at night, she knows when feeding time is and comes out to eat. She occasionally approaches us but will not accept affection. She will eat a treat out of my hand but if I try to pet her while she is eating it she scurries away/turns her back on me. She has moments when we see what we think is her true personality but she disappears from 8 am to 5 or 6 pm every single day. She does not seek out patches of sunlight, she just started climbing her tree and looking out the window at night. We are using Feliway diffusers and VetriScience Composure treats. We have provided beds, blankets, scratching posts both vertical and horizontal and all textures (She will only scratch our bedroom carpet, she will not use a post), toys...everything we can think of. She was hiding under the bedroom dresser all day so we blocked it off and now she is under the bed all day. We are just heartbroken that we can't get close to her and earn her full trust. Any advice is welcome. Thank you.
