I know y'all have covered this a million times but I'm new here and need advice. I have two siamese. Siblings, 8 years old. I am getting a new kitten this evening. Also siamese. It has been recommended to gradually introduce the kitten but many have told me to act like the kitten has always been here, just provide seperate food, water, and litter box. BUT to show more attention to the *seniority* cats. Advice???? Thanks!
