I've got two 6month old ragdoll kittens a boy and a girl we've just introduced a two year old adult ragdoll cat female the adult is getting on OK with me but not with the kittens she hisses at them when they come near herbut they haven't had a fight have you got any ideas that might get them along better?

It will take about 2-3 weeks for the kittens to settle basically you have brought another cat in that a higher pecking order they have there noses out of joint they will get over it eventually and calm will once again rain, just make they all receive the same amount of love and cuddles and keep it as normal as possible there just being protective of there territory all cats are the same I know my two are going to go crazy when we get our new kitten.
I must say ragdolls are beautiful I would love a Norwegian forest cat I just love cats I would like them all hehehehe.
