Mine are almost 3 years old and still do that. They are never seperated from me and will only eat when Im there, always in the room with me, they have something against closed doors, including shower curtains (they whine when Im in the shower and will watch me with both paws on the ledge of the tub looking in!) LOL they don't stay in bed when I get up to pee in the middle of the night, they gotta follow. If they are sound asleep on the couch and I get up, they wake up jump down and follow. If I pick up one the other MUST be picked up also. If I hug or kiss my boyfriend they are all over us jumping on our legs... they do not tolerate me giving affection to others!
Yet I find all this oddly sweet and endearing! Actually if one is not at my feet and I call and he does not come, I panic inside for a brief moment.

sad huh?
