IF tu already have an older cat in the house mostrar him/her that he/she is superior to the kitten. If this does not happen the older cat will grow to hate the kitten.

gatitos amor attention and want as much as possible but if the older cat is in the room, tu must pay attention to the older cat. Even if tu want to pet the kitten tu must pay attention to the cat.

gatitos don't need as much comida as older gatos so tu really only have to feed them when tu have meal times.

gatitos are very entergetic animal so tu can not keep them capitve in your arms, they will hurt themselves. Also keep anything off the floor that tu don't want broken. They tend to play with them.

I know this things because I myself have a kitten and cat. When they first saw each other they hissed and spit, but now they are best buds that only get on each others nerves sometimes ;D
