Yes, the average cat does expect a lot of love and attention. Cats are not always outwardly loving to their people, but usually the person looking after them can expect an affectionate rub of the chin or a greeting at the door. A well-loved cat will purr a lot which is also a sign of contentment and affection. On the whole you can't expect as much love as you give, but rest assured that it is there, otherwise the cat would run away if it has half a chance.
