We have had our kitten Token since he was 4 weeks old. He is now 12 weeks, and we are planning on getting a half-siamese kitten in three weeks. We will be introducing the two, but I am not sure how the older kitten will take it. The younger kitten lives in a house with like 10 other cats, so I think he will be okay. Token has not seen another cat since he left his brothers at 4 weeks. He is very spoiled and very attached to us, so I am unsure how he will taken an intruder. I was wondering since he is still so young, if he would adjust to another kitten more readily. He will be getting neutered probably before the other kitten comes home. Does anyone have any experience with this kind of thing? I know that there have been some posts about introducing an older cat to a new kitten, but not two young kittens.
