Hello, I recently lost a beloved Persian named Little Bit to kidney disease in February. I have 2 other cats. One is around 8 and the other about 5 named Cassie and Sissy. Both are rescue cats that I have had for several years. After my Persian died, I decided to adopt again after a few months. I adopted a beautiful little 8 month old cat/kitten whom I named Chloe. I have kept her separated from the other 2 in my bedroom, and only let them see her periodically and with supervision. Cassie tries to get along with Chloe, but she is a big cat, and when she passes by, Chloe sometimes becomes agitated, gets defensive and has attacked her. Sissy is aggressive to Chloe, and has tried to attack her as well. So I am forced to keep Chloe separated from them for safety reasons. I have introduced new cats to each other before, and never ever had this issue. I have tried Feliway with no luck so far. I really want these 3 to get along without all the cat fighting, but I don't know what else to do. Sissy and Cassie get along fine on their own. Does anybody have any ideas as to what I can do to get these 3 together and at least learn to tolerate Chloe???
