Yesterday I paid a birthday visit to my friend who took in Koda. They have had a familiy with kids visiting before me, which was pretty loud. So Koda was quite tired and relaxing in his hammock, but he still was curious about what's going on.
Gestern habe ich meinen Kumpl, der Koda bei sich aufgenommen hat, zum Geburtstag besucht. Vor mir war eine Familie mit Kindern zu Besuch, was offenbar recht laut war. Also war Koda ziemlich müde und hat sich in seine Hängematte verzogen, wollte aber trotzdem noch wissen, was um ihn rum abgeht.
No matter how domesticated a cat is, their natural instinct will often be to sleep with their eyes partially open. You may even notice their eyes moving around while they are still asleep.
Predators hunt! And they certainly don't want to be hunted in return.
Fun fact: Cats are also capable of uni-hemispheric slow-wave sleep where they sleep w/ only half of their brain (one eye open, one eye closed)
