if another cat come to your home, your cat will be friendly to it ?

It'll take time, but I've never met a cat yet that wouldn't eventually accept another cat. When my roommate got hers it was a constant battle. Mine hated him. She's yowl and screech and claw at him and hiss and snort.. she was one angry kitty. That was in December and now they're pretty much completely fine with each other, a few scuffles here and there, but it's minor.

Hello Sallyxu! If a cat or a kitten found her way at our house, my cats are very friendly to her they will share their own food to the newbie. I'm really proud to them because they are really friendly. There was a time that I found a white kitten that was lost I put her in our balcony then after a few minutes my black cat goes to the kitten and then she bites her neck softly then lifts her up then she put her in the box where my black cat's kittens are in. My black cat fed her with her own milk. I was really proud to see that my black cat was giving.

I don't think there is any cat who will become friendly with the new one .She will be jelous of the new one & try to attack her.They are like that only.Only the sibblings are friendly but till they are small.After that they will become rivals.Its there nature.They like to have all the attention.

i think it will be a great war between them.
