I have three cats but my problem lies with two of them. My older cat, Maggie is 7 1/2 years old. About a year and a half ago a cat showed up on my door step and I took her in. I tried to find her people, ad in news paper, went door to door, and the like with no luck. To make a long story short she adopted me. I named her Callie. Maggie was not too happy with the whole thing but I thought she would get used to it. As time went by things went from hissing and spitting to growling and fighting. Now Maggie seems to be terrified of Callie. Maggie has even started pooping outside of the litter box. I even put a litter box in my bedroom which is where Maggie hides most of the time. I don't know what to do. I have grown very fond of Callie and don't want to get rid of her. My third cat, Sarah, is about six and fights back when Callie tries to bully her. Amy suggestions?
