OK, somebody please enlighten me. My 10 year old cat, is new to a split level apartment block. There is another resident cat in the building. I don't even know if it is a male or a female. The resident cat is quite large and as it appears from it's behavior, it seems quite territorial. This cat is also much larger then my cujo. Fights are happening, and I am fearful for my cat. Cat fights are scary. The resident cat has cornered cujo on occassion and there appears to be a lot of hissing and growling at one another. I want to protect cujo, by scaring and yelling at the other cat. Whats happening? I really would like for cujo to be the dominant cat in the neighborhood, but I'm not in charge. Hearing the fights, leaves me unsettled. What's next?
