The resident cat will expect respect from the new arrival. This usually starts with ears laid back, posturing, hair raised and possibly hissing or spitting. Then it may include sudden attacks by one cat and flight and defense by the other. Sometimes screeching and growling also occurs. This “fight” is to show which cat is dominate or territorial owner, normal for cats, once ‘top cat’ is determined they will peacefully coexist. They will have to be separated should they continue this “ceremony” for more than a week.
Have patience and don’t interrupt or separate them, any interruption will only cause the “ceremony” to begin all over again when they meet again.
Soon the resident cat will approach the new addition which will lie on its side, claws out, ears laid back growling softly ready to defend if needed. The resident cat will back away inviting the new arrivals curiosity, as the new arrival advances forward, the resident cat will growl and spit to prove who is “boss”. At this point the Cat lover can hasten the acceptance by petting both cats at the same time.
