I've recently adopted a semi feral cat ( 3 weeks ago) she was spayed last Friday and I've been looking after her in one room. She still hides much of the time and won't eat or come out while I'm in the room. Sometimes at night I hear her crying and looking out of the window. I have another cat ( also an ex semi feral) and wondered how long to keep her contained in the room and how to introduce her to my other cat. Any advice would be really helpful. Although I've tamed other semi feral cats, she is different because I bought her into my home whereas they choose to come in themselves after a period of time feeding them outside.
