I have a 4 year old tabby named Ginger who has been with us since 3 months. We recently decided to add a kitten to our family and to give Ginger a playmate. We brought the kitten home and Ginger showed a great deal of curiosity until the Kitten began crying. Then Ginger acted terribly afraid, ran and hid where no one could get her and stayed there for 3 hours. After a couple days we began 1 hour session room swaps. The kitten explored the house while Ginger begged to be let out the entire time besides the time she spent eating the kitten food. We then put the kitten in a carrier and let Ginger into the room after 4 days of this and Ginger hopped up on the Window perch and began growling and hissing and everything else. Treats, attention nothing would console her We opened the door and she haulled butt back to her hiding place. We tried this 6 more times over a period of 4 days and the same result. Desperately trying something different, we let the kitten out into the house with Ginger and the kitten chased Ginger around the house until Ginger went into her hiding place and backed up against he wall and went into a rage screaming. I dont know what to try next as it appears our 4 year old cat is affraid of our 3 month old kitten.
