My name is Pandora!

I was given Pandora 4 years ago by a friend, she mostly gets along with my other males cats, however I have never been able to get her to warm up to my other female. I have tried everything from anxiety meds to hormone diffusers and calm treats. Nothing works, she just relentlessly attacks the other female. I have to keep her in a separate room. I want her to be happy, so I need to find her a good home. I think she would do well with less people and less animals, I had several dogs and several cats while she lived with me. She is very sweet when alone with me. She is an indoor cats, but has accompanied me in my garden during cool times of year. She will come with wet food and a small carrier.
