Of my 15 cats only one is declawed(will NEVER do that again!), Stitches. He is picked on constantly by several of my other boys. All are neutered so I know it's not that. Stitch was always a sweet, layed-back kind of guy. Now he just seems so very sad. He spends most of the day outside now, but when my Big Mo (a huge Maine Coon) goes out he hunts Stitch down and corners him. Do you think they know that Stitch can't defend himself? Any thoughts? Also, he is the only one that they do this to.
