Has your cat/one of your cats really bonded with one member of your family?
I have 2 but my male and I are very close. He often comes up to sit with me, when I go off to bed he follows and knows exactly where I'm going - perches right on the bed and settles for the night.
He's a bit under the weather at the moment because he's got an ear infection but despite this he's curled up right next to me. If I move a seat he wakes, jumps down and comes to my new spot.
My girl loves her fusses as well and I do try my best to give her equal attention because she's just as loving. But Theo can get quite jealous over it at times.
