Things are much calmer in my house since I began using Clomicalm a few years ago. Medicating my cats was a last resort but things got so bad; Specs and Boo were fighting every day, then the peeing wars began and I'd had enough. Sometimes, though, no matter what you try, there will be cats who just do not get along. I think it's just like people; some of us just don't hit it off w/others and there's always tension there. But I do think that if Pollux gets more attention, things may calm down for you a bit. My Specs needs more attention and sometimes I'm lax in that department because I may be focused on Puddy, who's a CRF cat, or Creamsicle, who's a CH cat, and I'll notice the difference in his behavior. He becomes very whiney. I had 8 cats until my Peeka passed over and now 7 is all I can comfortably handle. Sometimes I think it isn't the number of cats you have but their personalities. I had a lot of chaos when I only had 4. Good luck and let us know how things are progressing.
