Cat overly showing dominance.. advice?

This is completely normal and something they have to work out. As long as there's no bloodshed or actually anyone getting hurt, they're fine.

It's ok - I know it's scary (geez, how I remember worrying because Dante is twice the size as Dharma), but as Stephanie said, if no one is getting hurt, it's ok while they work things out. I can still vividly remember being woken out of a sound sleep by a loud yowl - I race out with towels in my hands, in case I had to separate someone, but all I saw were two cats looking at me, like 'why are you up, Mommy? Nothing going on here'.

I know you're doing it, but try to remember to make a big deal of greeting Monet first, every single time, feeding him first, everything else. If you can, try playing with them, lots, so they're too worn out for any hijinks. Also, what worked for me was every time mine were 'nice' and hanging near each other with no 'looks', I'd give them a tiny treat, and praise them to high heaven, always starting with the 'old' cat first.

Also, while I was convinced my big boy Dante was picking on my poor little girl, I finally realized that it was really more half and half - sometimes my little angel girl would deliberately 'bother' Dante into chasing her.

Sure, there will be times when they annoy each other, but I suspect you're not seeing a real honest to god cat fight - just Monet putting the little whipper snapper in her place - and Picasso, especially now that she's feeling better, is probably totally full of energy and making sure her big brother doesn't have much quiet time to himself.

When I brought Dante home, I did that whole segregation room, etc. Looking back, I'm pretty convinced that for my two, it was not the way to go... Dharma just knew there was another cat in that bedroom, and she got really mad when I'd go back there, even for 10 minutes. And Dante was desperate, I think, to join the family - he hated being by himself, and I honestly think some of his litter box issues at the time was due to the stress of being integrated.

The first few days were filled with chasing (poor Dante got chased off the bed several times, each and every night, for three evenings, and then for about a week one slept on one side of me, and the other on the other side - I felt like the Berlin Wall). After maybe 2-3 weeks things adjusted pretty much - but I still remember how happy I was the day I found them staring out the window, inches from each other.

Just hang in there and try to stay very very calm - they do pick up on our emotions so quickly.

Totally normal. I have a brother & sister siblings. Boy is 12lb, girl is just 8lb. He's dominant of the pair, first to do everything. He will lick, bite, lick then bite her on neck, back, some yelping and hissing from her going on. But my little princess, she starts too! Getting to him for attention, chasing him, swatting at him. They really love each other. He will lick her, she will lick him, constantly. She will search him out, and they'll come together, she will lick his foreheard, its indearing. They eat sleep play together. Both fixed. It's just cats life, don't worry. One will always be dominant. It's great you have a male/female combo. They will really bond, he will always protect her. I agree with reinforcing status, my boy gets everything first, well, he demands it anyway . Girls gets same amount of attention, just after him.

If you're still nervous, maybe try feliway?

In my sig picture, the cream cat is my boy, calico is the girl. You can SEE THE LOVE THEY SHARE.

Don't Worry.If there not hurting each other they should be fine
