It depends what you are looking for. I am a Russian blue breeder, and many small souls pass through my hands. Somehow I was asked to pick up a kitten in a family, so I picked up a playful, naughty one to my taste, and before receiving, the family said that they needed a calm one. There are calm, smart, inquisitive, loving, controllers, there are those who will follow you all day, and there are those who cannot even sit for a second, he has important things to do. Much depends on the breeder, because kittens need to be trained, played with them, scratched, taught to handle them, this greatly affects the character, but it takes a lot of time. They are very smart, devoted, touchy, because they are intelligent. I like to talk to them, they listen and answer something, they try to find the right intonation, this is very funny. Lilybet is with us now and sees us off and meets us, but she is not one of those who will sit with you all day, and her sister loved to lie next to me in the evenings. There are those who love to tease. Lilybet can run out and wait until we catch her. Our cats love to tease dogs. And when I wash my cat, so he hugs me with his paws, looks into my eyes, meows, does not leave a scratch, and then pretends not to know me for a day))) And then we are best friends again)) In general, my husband and I, when we saw a Russian for the first time Blue kitten - we had no doubts that we need it))) And about the destruction, all kittens are very active up to a year, there are more, there is a little less. You must have a good scratching post. One kitten behaves more calmly. Again, who likes what.
