Sometimes Foo would flop so well that I would walk into the kitchen, see her sleeping, say her name and nothing. I would stand there for a minute trying to see if she was breathing, but I don't see so good. So I would have to either have to run over to her cage or scream from where I was because I would be frozen to the floor. I scared the crap out of her A LOT. She was like Monty, with the eyelid and the scary.
Ellie doesn't flop like that, she stretches out but not a full on DBF. She isn't that comfortable yet.
But Monty is beyond comfortable! I actually envy the relationship you and Monty have.
