I hate our cat

Let me start by saying I brought her when I was 16. I adored this cat gave her love attention affection and constantly feed and played with her. Now she has bonded to my father and literally only cares about food. She legit heavy breathes while I’m sitting at the table eating.. she only comes near when there is food.

This is an indoor cat who is feed twice a day minimum and she gets lots of food!! She destroys furniture pees outside her litter box and hisses at the dog.

It seems like there isn’t much I can do about the cat they aren’t trainable.. her personality is horrible so food centred. She has literally made me hate cats which is sad cause I know they aren’t all like this. Also I am used to dogs who love you and are always happy to see you..

I need a place to vent I can’t tell my family as they all think I’m targeting her or it’s normal.
