Sophia, you are one lucky gal! Welcome to PT.

If she spent all her life in a barn / outdoors, it is no wonder being inside is a bit scary. All those close walls and low ceilings! But she is also used to having other cats around her, so it makes sense that she feels better when she sees Hermes. Good for him to be getting along with her!

She will come around to living the life of a spoiled kitty, I am quite certain. Hooray!
