Queen Zola's reign has begun!?

I just got a 2nd bengal cat. My first one, Iro, would cry all night, so after much research we decided to get another bengal. I went out all the way to Long Island to get her, Zola. After I pick her and we get back home, Iro freaks out when he sees us carrying a carrier. (I think he's claustrophobic) goes running full speed underneath my bed. Then we put her in her own little enclosure so she can get use to the house and here comes, Iro, he seemed curious about her and the first thing she does is growls at him. I thought it because she does not know who he is. Can I get some insight about this solution?
