Yes, it is much too soon to make such a fast judgment and I don't think he is mean, he is just starting to show more of his true personality, remember I told you that you were in the honeymoon phase and he was on his best behavior but now he is starting to unpack his bags and you will see more of the true Timmy. Not to alarm you but it will take time, a lot more than 11 days, you must learn some patience for you will need it in the coming weeks and months. Please just allow him to settle in and don't take his behavior as a setback, definitely don't take it personal, he is a wild animal and his trust has to be earned. Otherwise I think you are doing fine, if he thinks you are too close to him then back off some as you may be trying to rush him for more than he will allow, take your time and see what happens.
