When we lost a cat two years ago, I said to his brother that now he would need to spend more time with DH, as the cat who died had spent time with him. The survivor was and is very much my cat.
Since then MY cat spends time every morning cuddling DH.
Years ago I lived in a flat with a long passage between the kitchen and dining room. The cat I had then loved walking as slowly as possible through this narrow passage just in front of whoever was trying to walk there. This was highly exasperating to humans, but a great game to the cat.
When my mother started walking badly, the cat stopped teasing her in this way, but continued to tease the rest of us.
Later when my father started walking badly, the cat showed him the same consideration.
