Recently I brought home my new kitty Pandora, who is a very lovable cat. Problem is, I have another cat, Storm, whom is very upset with this, in which is understandable. Jessie, another cat I have, isn't bothered at all and befriended Pandora. Storm continues to hiss at Pandora, I'm assuming this is a jealousy issue because I've been through just about everything with Storm, but does anyone know what I can do to help them get along? I hate to see them be miserable like that.
