Yes, he's neutered. : )
He's not very playful but he has become addicted to being combed!
And I think that does make him a bit calmer, when I comb him at night...
As for food he always had food left, but he wakes me up at 5 am so that I pet him while he has his night snack.
Some people say I've pampered him too much, which might very well be the case, as at first I didn't know I was going to keep him... I wasn't trying to get him an education, I just wanted him to feel welcome.
Anyways, he only started the loud meowing when he came back from his «other» owner.
