Next door's tom cat seems obsessed with my seven month old (female) kitten. I came home last week to find him in our house. He had been terrorizing her. She had 'pooped' herself and her 'private area' was covered in what I can only describe as 'gue'. Why is he so interested in her? She has been neutered! We now have a microchip sensitive catflap but i'm terrified everytime she goes out.
