Help - huge aggression issues while we temporarily moved in with family

Hi, I need a little help. We had to move in with my wife's family while we wait for our house to be ready to move in to. We're bringing in two cats, and there's already a cat here. The cats have been kept seperate for almost two weeks, but Milo keeps trying to get into Raza's room. He howls all night by the door and tries to get in. She hisses at the door, or anything that smells like the new cats. A face to face meeting doesn't get past growling and attack-poses. They are both alpha-types.

Milo has now agressively attacked and bit mom, dad, and sis, and growls when any of us pick him up. He is usually a "hold-me" cat.


We just integrated Milo and Copper a few weeks ago, and had to abrubtly move as well. I understand there's a lot going on in the kitties' lives right now.

The cats are clearly unhappy and the family is fearing death by cat-bite, please advise.

I would recommend getting a couple of Feliway diffusers and put them where the cats are being kept. This will help the cats de-stress.

This article has a number of suggestions for introducing cats.

Are the cats spayed and neutered?

It sounds that Milo is having the most difficulty with the new intro and temporary home with another kitty, he is probably extremely threatened, confused,lost, and stressed out! I don't know much about diffusers, but I would think he needs to feel safe and more in control of his surroundings at this point. Is there any way to keep him in a room that the other kitty isn't directly on the other side of the door? He is basically in shock/stress mode, and needs to collect himself, feel some control of his surroundings.

Basically, we split the cats up like this:

Milo and Copper get to have the run of the house in the evenings, until morning. Then during the day, they go up in the room I'm staying in, which has their food/water/litter box. Raza then comes out of her room, where her food/water/litter is. The rooms are seperated by a bathroom, and the cats never pay any attention to the bathroom door. Through the hallway is where milo will do his aggressive stuff.

Maybe tonight will try putting them in a different room across the house. Thanks.

You could also try flower essences. I have seen some amazing changes by giving our cats Rescue Remedy when they're stressed, etc. Cat Faeries has some really good specialized ones. Flower essences can be used in conjunction with Feliway. Here's the link:
