Kittycats like to climb and jump all around and they need a comfortable cat bed to sleep in.

I not too sure if I use these words "jump all around" and "sleep in" correctly in these sentences.

Cats are famous for sleeping anywhere. If they use a bed they don't use any blankets or other coverings so we'd use "on" rather than "in".

The sentence about them jumping would be more natural without 'all".
