Has anyone had a rescue cat with behavioral problems……?
That sounds like “fear aggression” to me. In the behavior department of the San Francisco SPCA where I was trained as a cat behaviorist this cat would be a “Level 4” and she would be worked with for a long time to help her overcome her fear of humans and make her an adoptable cat. The cat has conflicts between her desire for human attention and her fears from past experiences in her life. I wish you would go to www.littlebigcat.com and read Dr. Jean Hovfe’s article titled, “Flower Essences for Animals” as using these on animals can really work wonders in changing undesirable (for humans) behavior and help the cat emotionally to clear her psyche of past bad experiences, moving her “rehabilitation” along more swiftly and successfully.
