Thanks for all of your replys. Cirrus has been here for 5 months now and it seemed like he and Storm were okay in the beginning. I don't know if Storm chases him when I'm gone but I know he's still doing it when I'm here because he did it 2 more times today. This evening I decided to spray his face with some water and it seemed to help. Last night Cirrus hid under the bed and slept there most of the night. I don't ever recall him doing this before.

I'm trying to let them work it out on their own terms. At least there's no bloodshed. I've always been very lucky in the past with all of my cats accepting the new additions very quickly and easily. I guess I got spoiled. I'm sure that eventually they'll work it out or learn to tolerate each other better. I'm trying not to worry too much. BTW welcome to Pet Talk Siva's Mom. I'm sure you'll love it here.
