he is a sturdy breed, big body and he will live forever. i have always wanted a big sturdy cat like your Russian Blue, they are big marshmallows and hopefully yours isn't too shy of people at first. the boyfriends is on his parents farm and he keeps breaking his arm so they have had to re-break it to straighten it...he gets nervous when you pick him up until you pet him and he trusts you and knows that you aren't picking him up to realign his arm. you have to approach him because he is shy. he looks just like your big boy.... only his right arm from his wrist down is bent outward at a good 85%. hope to see more of him!
