I like cats, they are entertaining once you understand them. I grew up with them. I don't have one anymore, but they are cool animals.
The cat likes you obviously, and as long as you don't pet it or feed it, it shouldn't follow this trend for long. Once a cat really likes you and you show it attention, they will remember you forever.
Now when a cat hates you it can really make life hell. My brother's girlfriend has this demon cat, it would jump in your lap and once you tried to pet it, she would bite the shit out of you. She always looked friendly, but the minute you got near the cat it would go nuts. It liked my brother and his girl, but it hated everyone else. It would piss on your clothes or worse. It was the only cat i ever didn't like. Fucker would attack the back of your leg full force at 3am when you were walking to take a piss. Little bastard fucked my calf up one night and i wrapped it in a towel and threw it on my brother's bed. I woke up on the couch and it was curled up by my knee, once i went to move it bit the shit out of me and literally attacked me full force for like 30 seconds...it was a devil and survived cancer already.
