I think it is always good to lay in a doorway- this way you can see any danger coming from any direction.
Plus they cannot close your escape way!
On the other hand make sure they don't trip over you- humans are so clumsy!

P.S. Lucy, be careful. Being black puts you at even more risk
Like poor Newfie Teddy who could have been seriously hurt when his mom tripped over him. She had been sitting in half dark at her computer and did not notice him when she got up. Thanks goodness nothing bad happened to him. It was her who broke her knee.
