New Kitten, But my cats hate him Options

[gillian]

2 days ago, I rescued an 8-week-old male kitten. He is gorgeous, with long dark brown hair and big green eyes. I've named him Sebastian and he's joining my 2 dogs, my other 2 cats, my 2 birds and my 3 fish. lol.

My 2 cats saw him through the kitchen window and were growling and hissing at him; they're refusing to come indoors now he is here.

It was like this with my cat Sasha, when I brought 7-week-old Darcey home. She hated Darcey just as much, and even now 2 years later, she still dislikes Darcey, and does little but growl and hiss at her. She won't come near us if Darcey is near us.

Now poor Sebastian is getting the same treatment from both Sasha and Darcey, and I'm worried it'll be like this forever. I'd thought perhaps Darcey would get along with the new kitten as she is normally a lovely affectionate cat. I'd never heard her growl or hiss before until we brought the kitten home.

I know these things take time, but its been 2 years and Sasha still hates Darcey, even though Darcey doesn't do anything to provoke Sasha.

How on Earth do I get my cats to get along???

Below is little Sebastian.
