My name is Helder and I'm the owner of two cats. A 4 year old black female called Ali and a 3 month old black and white kitty called Pixie, which I'm trying to introduce to Ali. That's mainly the reason why I joined the forum.
Welcome Helder. You shouldnt have any problems introducing a kitten to an adult cat. Normally they are very tolerant of kittens. They will cuff them or put them in their place once in a while. But Kittens need to learn from the adults what the rules are in the cat kingdom.
