I've just had my boy neutered and he's 18 weeks old so i'm sure yours is old enough to be 'de-plummed'! lol!
I would be tempted to get him a friend though.....cats are very loving and can be clingy especially if their first playmate is a human. My cat Audrey used to be the same with me when she lost her brother, i then got her the two boys for company and she adores them. She's still very loyal to me but she loves nothing more than playing with her two brothers
