I have a cat named "Lady", we have had her for just over 3 years. About a month ago we took a friends cat because their son became allergic. She is about 5 years old and named "Spotter". They are both fixed. The problem we are having is they just keep growling, hissing and even fighting. We have had adult cats in the past with new introductions and usually this behavior only lasts a week or two. We want both of them to be primarily outdoor cats, Lady is and Spotter is indoor/outdoor. Should we just continue to let them fight it out or should we rehome Spotter?
