New kitten in house added to family

I just recently adopted a new kitten and I have another cat about five years in age. I am wondering how long it usually takes for the older cat to get use to the new one. I have had them seperated since I got the new one. (which was only Wednesday, June 2). Also, my older cat has just recently starting growling at me, and hissed only a couple of times which had never happened before. Is this all normal?

Sounds pretty normal.
There's a lot on this site on the subject.
My old cat hissed and growled at a new additon (and me sometimes) for a week or 2- gradually decreased.
It was constant every time she saw him for about a week.
My young one loved her from day one and she never got a reaction from him- and she was never aggressive towards him- just upset.
let the kitten have the run of my home at night after about 10 days- left them together during the day after 2 1/2 weeks.
It takes time- mine were playing together within weeks- but there was the occasionaly hiss for a while.
Good Luck
Catherine

Welcome to TCS and congratulations on your new addition! May I suggest this
for starters. Hope you will find it helpful. The experts here will be more than happy to answer all of your question!

hello and welcome to the site

My cats have been together for twelve years, and Felicia still hates Beau.

Please continue the slow introductions:

Additionally, a kitten can sometimes be a bit overwhelming for an "older" cat. That is why many groups actually suggest getting 2 kittens so that the kittens can play with each other and the older cat can determine whether he/she wants to join in the action or not.

As far as your cat growling at you, it may be a result of you interacting with the kitten and thus smelling like it.

There is a really good thread called at the top about behavior issues and in that thread you can click about introducing a new kitten/cat to an existing one..there are many good suggestions in it.

Thank you for the information. I have been following the advice from this site, and I do believe that my older girl was more mad at me than the little one. Thanks again.

My eldest is two years old, my youngest when i brought her home was 6 weeks old.

Rosie(the eldest) hated not only Sophie but me as well . She growled at us, hissed at us, and she stayed upstairs in the spare room all day and night until curiosity got the better of her.

Rosie kept following Sophie around the house, again i think out of curiosity as to who this "stranger" was in our home.

It was all quiet one sunday afternoon, i dashed upstairs to see what they were up to?, and there they were fast asleep "together" on the bed.

Just take it one day at a time as i did.
