My name is Missy!

I had been looking for a 2nd cat. My present cat is a three year old, male, very outgoing and playful. When I saw this one year old female listed on Next Door, I thought this would be a good match. The person could not keep Missy because her cat would attack Missy and so had to keep them separated. Missy is a beautiful cat, grey with orange, very silky, shorthair, very affectionate but she will not let my cat near her. She grows/hisses. This has gone on for more than six weeks. Once she urinated on my sofa exactly where I sit so now she is back in my 2nd bedroom and let her out when I can watch her. I will be having guests in a couple of weeks and only have two bedrooms so it is not a workable situation. She has not urinated again - I assume that was some kind of statement. I recommend a house where Missy would be the only pet with someone who wants a cat to sit on their lap, curl next to them when they sleep.
