Any cat behavior experts out there? I have some "kitty quirk" questions...?

[mamamaine]

I currently have 4 males, all related and ALL neutered. I have the daddy cat and 3 of his sons, all brothers, and they have been with me since they were born, even the daddy who is about 2 years old. The 3 brothers are a year old this month. One of the brothers, Petey, is a very needy and vocal fellow who seems to be a bit hypoglycemic. He cries a lot to eat and after I feed him he wants to be held. He will follow me around crying (sometimes he even vocalizes "mama" in his meows) and won't settle until he is cradled in my arms. The other 2 brothers are not as needy, but the largest cat, Moe, will come in and jump on my bed, get in my face and meow like he is talking to me...and will try to lie down in or on my face! The daddy cat, Boykittie, is also very vocal and also says "Mama" when he comes in at night. He will only lay down in my lap and purrs VERY loudly and does the kneading thing until I get up. Boykittie was the runt of a litter, born breach with a deformed leg and foot that healed itself. I did bottle feed him and hold him alot when he was a kitten so I know he thought I was his mom...I just didn't think he still felt that way? The boys were a litter of 5 and we did find homes for the 2 little girls but the boys ended up with us. I have never had cats (especially males) that acted this way before and they only do this stuff with me. Maybe someone can explain a little better and advise what, if anything, I should do. I love the fact that they are all affectionate but it gets to be a bit much...I have to lock my bedroom door at night or all 4 would crawl in with me. They don't fight, they all get along fine and play together for the most part. Thanks for reading this and answering, I love my guys and just want to understand them better.
