I think their behavior is also affected by where they got their start. Mimi has been with us since she was a tiny kitten. She has a loud purr, loves to be held and loves sleeping as close to us as she can. Butter, on the other hand, has had very few moments of "cuddling". He does let us pick him up and on occasion, he has jumped in my lap, but you really have to let him decide when. I am sure it is because he was a stray and didn't come to live with us until he was probably 3-4 years old. But you know what is the most redeeming thing about Butter? He stayed, and he doesn't ever venture far from us inside. He sleeps on the bed with me, not close, but he's there. And usually, he wants to be in the same room with one of us at all times. Even outdoors, he prefers to hang out in the backyard with the dogs. So his love is shown differently than Mimi's, but we know that both of them do love us in their own way! And we certainly love them!!
