2 months ago I adopted a 7 year old Male cat from the shelter. I was told he was very shy but once he warms up to you he loves attention and loves to sit on your lap & be petted. Well it's been 2 months & he's still afraid of me. If I'm sitting down he'll rub himself on my legs & let me pet him but as soon as I go to get up he runs into the bedroom under the bed. He will come to me when I give him a treat but when he's done eating he runs back under the bed. He started pulling at my rug & my walls, I bought 3 different cat scratcher posts. He will not use any of them. I put treats on them he eats them & walks away. I feel so bad for him but I dont know what I can do. I try to have conversations with him. He'll sit there & meow but again I start to get up & he runs off. Any ideas how I can help my baby???
