Introducing 2 Female Cats

Greetings everyone,

I have a 4 years old cat since 2 years.

2 weeks ago I adopted a 1 year old cat.

I have followed Jackson Galaxy's method on introducing two cats. I have taken it really slow; I allowed them to see each other AFTER introducing scent, peeping through doors and sharing meal times across the door. In short, I did all my research on introducing both.

Now when I allowed both kitties in one room my problem is,

They just sit there hissing and growling at each other. None of both came forward to at least sniff one another. None of both attacked each other (Thanks Goodness) But only the hissing and growling continues whenever they face each other. The result is my older/resident cat just backs off and moves out of the room slowly as if she gets scared of the new kitty. This has been happening from 5 days. Same thing.

Is this normal?

If this running away continues how will they get closer, sniff each other and make friends?

Am I doing something wrong?

Do I have to do something else?

Sorry for the long post, Please guide me.

I'm sorry I missed your post before this. How are things now?  

If they aren't fighting; that's a good sign.  Some stages of introductions just take longer than others.  It's completely normal for it to take a few months even.  It all depends on the cats.

Good luck!! 

I have a question. I have a 9 month old siamese tabby mixed cat and she is female. She is not agressive and she loves playing with my moms small dogs. I was just wondering if i bring home a new kitten if she will be as calm as she is with the dogs or if she will become agressive and try to hurt the kitten. What should i do?

This is completely normal when introducing any cat to annother. As long as they aren't getting physical, I wouldn't pay too much mind to it. They are just settling who will be the Alfa cat and other kitty stuff they need to settle. If they become physical or if they're still growling and hissing within a week, I would consider isolating them and trying again.
Try playing with one in the same room with the other, see if they will take to playing. Offer treats, pets, and talk in a calming tone to keep them at ease.
There is a product you can get online or at your vet called Feliway, it's iften used to help calm cats who are stressed over new family members. The pheromones lower anxiety and keeps them peaceful. You can get the wall plug in as well as a spray.
