I (20)f, sister (18). When my sister got the cat she never spent time with him. Ever since the cat has been in our house, the cat spends 90% of the time in my room and cuddles with me. She never allows him in her room and just say hi to him every now and then. He loves to watch cat tv and has a special self in my room just for him. Every time I bring up the fact I want to take him with me when I eventually move out. She gets mad and just says, "well hes mine so, no." I tell her that I'm willing to even pay her money for him and show her pictures of me and the cat together almost every day. I don't know what to do, or what to say to her anymore. Am I the asshole?
