Just brought home two adult cats to introduce to my other cats. At the moment, the two new guys are in individual crates in the bedroom with the door closed off from my resident cats. Here is where it gets weird. I let either cat out one at a time to stretch legs and sniff around. Whenever Jenkins, the tuxedo cat, is out and about, he chooses to cuddle up to Rigatoni, the orange one. He sits right next to the bars, sometimes even touching Rigatoni! But when I try to let Rigatoni out at the same time, Jenkins starts wild cat fights. Definitely not a play fight. He made me bleed when I tried to break it up. Anyway, just curious if anyone knows what's going on. I suspect it might be a territory thing, but I'm not sure why he would decide that so quickly, especially when he and Rigatoni arrived together. Any direction would be great.
