Is it just my Harvey? But I've never seen him blink or close his eyes when he sleeps... When he flops his eyes are wide open but I know his asleep cos I can slide him along the floorboards a little bit without him waking up but he's still breathing...
Rabbits have a 3rd eyelid which they have to look out for predators so their eyes are never completely closed.
Only bunnies that are completely relaxed in their environment and around you will completely close their eyes when they 'play dead'
This was my 1st flop ever. I had to stare at his tummy to make sure it was still going up and down. He wouldn't respond to his name. Scared the crap out of me.
