I always feel happy when I see a kitten sleeping with her sister, and her sleeping position is never the same.😁 That's what makes me sometimes justify their sleeping position but still they will return to their initial sleeping position. Even if they are sleeping on the washing machine with an irregular sleeping position they sometimes often fall from the washing machine.😅 Luckily my washing machine is mini and only about 1 meter high, so it won't hurt if they fall, now they are sleeping on top of the rice cooker box.😁
