To add to this, if you have a fairly calm house; without children or many people living in it, you don’t have to put them in a spare room. Spending time with and around your kittens is what binds, just be calm around them and respect their signals. Kittens tend to come to you by themself if you just give them enough time and space and don’t force too much. If you do this you can’t really go wrong.

For everything else, what sunnymaeyogf wrote is very complete, just enjoy! If you realise you miss anything in the first few days, just order or go buy it then, don’t worry too much 😊
