I recently adopted my first cat, he is about 6 months old or a bit older, they are not sure. He is really cute and the shelter told me to be patient with him, however it has been over a week and he is still meowing at night and not letting me sleep. He meows loudly as the night goes on and then goes to sleep around 6am which makes things difficult for me. I have tried to pet him a couple of times and he just hisses whenever I get near to him and then runs away. Even if I get close to him by accident he'll run away. The shelter told me that he had been adopted and returned by a house that had a curious 2 year old and I think that may be why he is so scared. He is a siamese mix and I heard they were very affectionate so I am a bit confused. Is this normal? How long will it take him to adjust? Does this mean we are not a good fit for each other?
