My parents have 5 cats - one old female, two old males, and 2 female kittens. The kittens are also almost a year old and they hardly ever leave their mom cat. I'm no expert on cat behavior, but my parents just let the cats do whatever they want. Only if the cats start fighting do my parents separate them. I think maybe you just need to wait a while longer and the kittens will decide to separate from their mom.
