Kittens loves sleeping together in an unexpected places

Yesterday, I visited my friend at his house, my friend is also doing a great work by rescuing many cats & kittens, always we work together to save cats here! While I was in my friend house I saw this cute scene of 4 kittens sleeping together in this place! this simulates being in the womb a bit since it's warm and cozy and they can sense the heartbeat of the other kittens.
