Lovely mumsnetters have given me lots of advice about my sociopath ginger tom benjamin. A brief history is that he is fat, very needy/affectionate, likes things on his own terms (repeated run ups at the bedroom door if we shut it, lots of angry shouting if we don't go to bed and get up on time...!)
Over the summer he's been out a lot and he's usually nearby as comes when called at mealtimes. We're sans cat flap and he comes in at 11pm ish for dinner and comes to bed with us and sleeps under the covers
The rest of the time if he is in he is shouting to be let out. He might come home once in 15 hours but shouts if we shut the door. Often he is at the back of the garden but won't come in.
I miss my cat that used to sit on my knee a lot. He is either out or shouting to be out and unsure why
