My kitty Maya seems like she's angry/in a bad mood most of the time. With anyone who tries petting or holding her. If I try petting her or picking her up she just growls, hisses and sometimes even swats until she's left alone, and if my mom or other people do, she does the same thing. Every now and then she'll lay down by someone for a while and let us pet her, but after a short bit, she'll hiss and run off again. I have no idea why she does this. She loves my Pomeranian though, and is always running up to her and rubbing on her/bathing her a lot. Does anyone have any idea why she acts like this?
