Sounds like my cat Misty. We got her from a shelter when she was a tiny thing probably 8 weeks old, she was ferrel and now she is about 13yrs old. When she was younger she was ok always skittish unless it's really cold then she will seek warmth like when I put a blanket on when I'm on the couch. Over the last few years she does nothing but meow sometimes with a horrible voice that is so annoying. My husband thinks she started this after our other cat died a few years ago. There is nothing medically wrong with her that we can tell.
She wants no part of the new kitty, the only one she's close to is Lakota, she always pets herself against Lakota. Other than that it's like she's miserable and doesn't want a thing but food from us.
