My name is Harriet!

My wife and I adopted Harriet a few years ago. She seemed to have experienced some trauma in her younger months which I believe led to her current behavior. She is around 3 years old. She will not interact with anyone except for my older tabby cat. She lives in constant fear of our younger cat and spends most of her time under the bed or a chair. Sometimes she is unable to eat because the younger cat will not allow her to eat. Harriet and my younger cat fight almost daily and I will come home to pieces of hair from Harriet all over the place. I don’t think it is fair to subject Harriet to this anymore and I am hoping to find a peaceful home for her. I currently have not been able to get close enough to her to take her to the vet for her annual check up.
