I do believe cats love their owners, I know mine love us to bits. Raffles, long hair black is all over us and can't get enough of all the loving. Rosie loves my husband and she flirts with him all the time, follows him around especially out in the garden. She only comes to me for her food
Another thing, cats know when they can trust a human who loves cats. We were adopted by a stray many years ago. Came up to Alan when he got out of the car, and followed him straight inside the house. Jumped up on the sofa and that was it wouldn't budge. We named her Holly as it was a few weeks before Christmas.
