Perhaps the most important personality consideration is the environment the kitten was raised in. We raise our kittens in a home environment, we share our living space with them. It takes a bit more time and effort but it is worth it and anyway it is a labor of love. Of course sometimes these Abys can be rascals.
Some of the queens we have purchased were cage raised and we can see the difference. Generally Abys are so affectionate that unless you're experienced or have two Abys, one cage raised and one home raised, you will likely not perceive a difference.
What you can do.
Felines have a 12 week period of socialization. This is the most important period in their lives where they get acquainted with their surroundings whether it be humans, dogs or even vacuum cleaners. We do our best to acclimate them while they are here but this doesn't mean that a new owner should think that the socialization job is done and they can just sit back.
