I have 2 cats that I HOPE I can bring with me as I move back into my parents house. They have a cat that is not that friendly....I have a very limited time to get them acquainted. My idea is to bring them over in a carrier, let them sniff each other, leave bedding with the 2 cats scent on them and take a towel that I rubbed over my parents cat that I can bring back home with me so they can get each other scents. How often should I do this? I don't have the 14 days that they always suggest.
